CHAPTER  ONE: THE NATURE OF MONEYWhat is money?Linguistically, naqd  (money or cash) is to distinguish something or  determine its reality and  meaning. The author of al-Qamus said: naqd is  to distinguish dirhams and other  items.
In economics, 
money has three properties:
1. A 
medium of exchange, as generally agreed.
2. A  
measure of value3. A 
store of wealth (1)Therefore, this excludes eggs for  example, even if some people agree  that they have Properties 2 and 3. It also  excludes money that is  annulled by government, or that in which people lose  confidence: it was  money, but is no more.
Property 1 implies 2 and 3, but  2 and 3 do not imply 1. Therefore,  Property 1 is enough in defining money, since  it implies 2 and 3. cf.  GF Crowther, Monetary Economics - A Primer: “
Old English pounds, money bills and share certificates  are not money, even though they have Properties 2 and 3.” Money must  especially have Property 1.
Hence, the definition of money (naqd) is,  “
Anything  that gains general acceptance as a medium of  exchange, whenever or  wherever that occurs and in any way that it  occurs.” Thus, 
this excludes promissory notes and cheques,  etc.
“
Anything” refers to whether it is 
intrinsically valuable, e.g. gold and silver, or  whether its value is due to 
external factors imposed in order to avoid chaos,  as is the case with paper money.
There is nothing to stop us accepting  this definition. In fact, it is indicated by the words of some of our ‘ulama,  e.g.
1. Imam Malik in Al-Mudawwanah, Kitab al-Sarf: “
If   the people were to agree amongst themselves on using skins (as money)  such that  these were made into coins and monetary units, I would  dislike these to be sold  for gold and silver with deferred payment.”
2. In Fatawa of Ibn  Taymiyyah (9:251): “
As  for dirhams and dinars, there is no natural or legal  definition for  these; however, the matter returns to habit and terminology. This  is  because the basic principle is that the objective is not these coins in   themselves; rather, the objective is that they should be a standard for  mutual  transactions. Dirhams and dinars are not sought for themselves.  Rather, they are  means by which mutual transactions are carried out,  and this is why they serve  as money … A pure means, the substance or  form of which is not an objective in  itself, achieves the objective,  whatever it may be.” In this last  sentence, there is an indication that 
money is whatever gains general acceptance as a medium of  exchange, whatever its substance or form may be.
3. Our sheikh  ‘Abdullah b. Muhammad b. Humayd mentioned to us that he read a quote of  al-Ghazzali which says that 
money is whatever is agreed or accepted to be considered  as such, even if it were pieces of stone or wood.
Therefore, we  
doubt the correctness of the claim that gold and silver  were created to serve as money.  This doubt is strengthened after our  analysis of the historical phases  through which money passed until it reached  today’s stage.
Money is thus whatever is agreed to be such, whether by  government authority or public practice.  Regarding gold and silver as  having been created for money thus lacks  support from a legal, theoretical or  historical perspective. However,  it is accepted that they have been more  suitable than other items as  money, and this is why the sacred texts mention the  ruling of riba  regarding them, whether they are in minted or unminted form. The  only  exception to this is that caused by manufacture, e.g. ornaments and   jewellery: the ruling of riba regarding these is a matter of  disagreement  amongst the ‘ulama, a matter to which we shall refer  later.
CHAPTER  TWO: THE ORIGIN AND DEVELOPMENT OF MONEYWith 
barter and the division of labour, there were  difficulties due to the complexities of life.  Therefore, money was  needed. In coastal areas, they used shells. In  temperate lands: beautiful items  such as ivory and fishbones. In Japan:  rice. In Central Asia: tea. In Central  Africa: salt. 
(2)Commodities turned out not to be good enough for  money,  with problems such as: (i) fluctuating value due to supply and  demand;  (ii) perishability and (iii) difficulty in transporting. Therefore,  
gold, silver and copper were used.  These were  vulnerable to abuse, since not everyone knows their weight  and value. Hence the  government intervention of minting coins in order  to guarantee quality and  weight.
The 
first to mint money was King Cryos of Lyddia, Southern  Asia Minor, 7th century BC; there are examples in the British Museum. In  the Greek civilisation, the coin was called drachma meaning “
a  handful,”  and the word dirham derives from this. This was fine, except  for the  problems of (i) transportation in large quantities and (ii) the risk of   loss or theft.
Paper MoneyThis was not something new,  for Marco Polo brought paper money from China in the 14th century CE. 
The first issuer of paper money was Sun Tung in the 9th  century, and this was continued by the kings of China and Mongolia. 
(3)There were  four stages in the 
development of paper money:
1. Merchants issued 
paper receipts, rather than carrying gold and  silver in long journeys.
2. Goldsmiths and money-changers issued receipts  for deposits, and these 
receipts began to be exchanged. This practice was  limited at first but it later increased until it led to the
  issue of receipts that exceeded the deposits, i.e. the extra receipts  were not backed by gold or silver.
3. This was now a significant change  in the history of paper money: it 
had Properties  1-3 plus absolute buying power. The  only problem was anarchy and  abuse, since all goldsmiths could issue receipts.  E.g. in 18th-century  France, Jean-Louis & co. 
issued too many receipts, and this led to a loss  of confidence [Crowther]. This led to 
state involvement, imposing paper money as legal  tender.
Thus, paper money was not just based on custom and ‘urf,  but fully supported by 
state enforcement of it as legal  tender.
Question: Is paper money backed by gold or  silver?Initially, the answer was yes,  except for extreme  circumstances, e.g. the Bank of England honoured  the promise (to pay the bearer  on demand …) throughout, except during  1797-1819 (due to the Napoleonic wars)  and 1914-25 (due to World War I  and its aftermath). After 1925, it honoured the  promise if the amount  was over £1700. Thereafter, there was total confidence in  the paper  money so there was no need to honour the promise. Hence, the gold   standard was abolished in 1931. Crowther: “
The  issuance of paper money needs to be controlled, but  this does not need  to be done with full backing by gold, as proved by the  experience of  Great Britain since 1931.” 
(4)CHAPTER  THREE: THE BASIS OF PAPER MONEYAny money needs 
public confidence, backing and support for its  function as a medium of exchange and for its buying power. This can be 
intrinsic, as with gold and silver, or 
extrinsic,  e.g. full backing by gold and silver,  property, shares, monetary  bills, etc. The backing can be by  government-enforcement – this is  usually only in political crises; e.g. in 1946  the British government  bought gold from the Bank of England to back its paper  money during the  Second World War.
The 
extrinsic backing can be partially with a precious  commodity, supplemented by government-enforcement.
Gold and silver do not need backing.  Governments  realised, like the goldsmiths before them, that paper  money does not need  full-backing. Due to economic crises in Britain  (1857, 1866, 1914 and 1931),  when the 
public lost confidence in paper money,  the Bank of  England and the government realised that the gold-backing  promise would have to  be withdrawn. Similar crises occurred in France  (1848-50), Colombia (1895),  Portugal (1848), Italy (1894) and Argentina  (1876, 1885). The gold standard was  abolished in the UK in 1931 and in  the USA in 1934.
In 1947 the US  government ordered banks to have a 40% gold-backing. In  1928, similar orders had  been given in France (35%) and Germany (40%).
Backing can be done with property,  e.g. in Germany  in 1923, public confidence in the mark collapsed. The  German government issued  the Rentenmark, backed by agricultural land.
Whether paper money is  backed by gold, silver, precious stones,  property, monetary bills, etc., the  paper money is not derived from  these bases; rather 
the purpose of backing is: (i) to instil 
confidence in the paper money into society, and  (ii) fulfil the 
requirement of issuing paper money.  Both of these  factors have lost their importance: (i) people using  paper currencies no longer  worry about the extent of its backing,  especially after annulment of the promise  to pay the bearer on demand …  (ii) most paper-money-issuing banks are central  banks. 
(5)CHAPTER  FOUR: THE SECRET OF PUBLIC ACCEPTANCE OF MONEY AS A MEDIUM OF  EXCHANGEEconomists have differed on this matter, taking  three viewpoints, each  of which could be correct for the period in which in  appeared.
VIEWPOINT 1: THE “MINERAL” VIEWBecause  of its intrinsic value, the money gains general circulation due  to custom and  government enforcement. Before being accepted as money,  it is a rare and  precious substance, e.g. gold, silver, bronze, etc.  When it becomes accepted as  a medium of exchange, it has no material  superiority over its substance, except  in rank. The American author  Conant says in his book, Money and Banks, “
Money  is a commodity having intrinsic value that is  acceptable in  transactions; law and custom make it a means to settle  debts.”
According to this view, 
paper could not be money, but only serve as a receipt for  money that is intrinsically precious. This view was the correct one  during the 19th century, but became obsolete once paper money was no longer  backed.
Critical  analysisAlthough paper is not precious, it definitely 
qualifies as money  and plays a leading role around  the world in trade, insurance and  savings, etc. It would be no exaggeration to  say that paper money is  now 
superior  to precious metals and stones in being  better for the exchange of  goods and services and with respect to widespread use  and general  acceptance. The 
definition of money according to economists and  monetarists  is that it is whatever is acceptable as a medium of exchange.   Therefore, precious commodities are only a subset of money. The  extrinsic factor  associated with money does not imply the money’s  intrinsic value, contrary to  this view.
As to the objection that paper money relies on backing by a  valuable  commodity such as gold or silver and the promise to pay, this is   answered by saying that
   economists and politicians allow the issuance of paper money that is  not fully  backed, and experience shows that this does not affect its  value. 
(6) The correct  understanding is that 
money  is whatever is generally accepted as a medium of  exchange, whether its  value is intrinsic (e.g. gold and silver) or extrinsic  (e.g. public  confidence and government enforcement). Cougarro says,  “
What  matters to the person in possession of an amount of  money is his  confidence that it will facilitate his buying of the commodities  that  he desires.”
As for the 
promise to pay, it has no effect in reality.  Everyone knows this, yet it has 
not affected the role of paper money as an agent of  general exchange.
VIEWPOINT 2: THE “GOVERNMENTAL”  VIEWThe 
value of money is derived from state authority and  legislation, 
without reference to the value of the substance  from which the money is manufactured. The 
state mints or issues money, sets its amount and value  and enforces it as legal tender for transactions.  The public do not  differentiate between precious minerals and cheap  materials as long as their  value is the same with respect to other  goods.
This viewpoint was known  and accepted during medieval times, when  rulers issued money and set its value.  Later, Viewpoint 1 took over  from it, but when Viewpoint 1 became obsolete,  Viewpoint 2 took over  again for a while. The German author Naab says, “
Money  is manufactured by the state, from which it derives  its power and  value. The value of the monetary unit is not intrinsic, but  derived  from the law that enforces it.”
Critical  analysisGovernment has 
authority and power,  but these are limited. It can  subdue criminal activity and rebellion  with military might and can solve many  social and economic problems,  but it does have difficulties. It is difficult to  enforce the general  acceptance of money for circulation and legal tender by  force of  government alone, without 
natural reasons for its acceptance and public confidence  in it. Government needs 
logical justification  for its policies in order to  keep the majority of citizens on its  side. If the state enforces money, it must  bolster it with measures to  inspire confidence in it as a store of wealth,  measure of value and  medium of exchange, even crossing the state frontiers to  serve as money  in foreign transactions.
History has proved this viewpoint  wrong. E.g. 
the issuance of paper money was mostly done by private  banks;  the state did not interfere by enforcing its acceptance. However,  it  enjoyed public confidence. In 1923 the German people lost confidence in  the  mark, which was the official currency, due to 
hyper-inflation. The German government issued new  money called the Rentmark, backed by agricultural land, but 
did not enforce it as legal tender. The Germans  abandoned the legislated legal money and used money that was not enforced by  law.
VIEWPOINT 3:  THE “PSYCHOLOGICAL” VIEWMoney is what people have confidence in as having  absolute buying power and serving as a store of wealth. This
  public confidence does not simply follow from (i) 
intrinsic value, otherwise unbacked paper money  would have no worth, or (ii) 
government enforcement, as with the German mark in  1923.
Public confidence is therefore wider  than factors  (i) or (ii), being based on many additional  considerations. E.g. money may imply  intrinsic value; political and  economic stability may imply balance in the  issuance of money,  safeguarding its principles and confidence-inducing factors,  protecting  it from forgery and excessive issue.
This viewpoint is sound,  extremely plausible and free from the  criticisms and objections to the first two  viewpoints. It neither  excludes money from Viewpoint 1 nor enforces Viewpoint 2,  but focuses  on public confidence and its factors and supporting  considerations.
SUMMARY OF CHAPTERS 1-41. Money is  anything that enjoys 
general acceptance as a medium of  exchange.
2. The 
original promise to pay printed on paper money has no  reality now;  it only serves as a reminder of the past and of the  responsibility of  the issuer in guaranteeing its value and limiting its  issue.
3. It is allowed to have some amount of paper money that is 
not backed by a precious commodity, although this  unbacked amount is usually less than 65% of the paper money in  circulation.
4. The basis of 
paper money can not only be gold and silver, but  it can be property or monetary bills.
5. The 
general  acceptance of money may be from its intrinsic  value, government  enforcement and/or anything else that guarantees this  confidence.
These points are the basis of subsequent  chapters.
CHAPTER  FIVE: ISLAMIC LEGAL RULINGS ON THE REALITY OF PAPER  MONEYPaper  money was not known to the early jurists of Islam  since it was not in  circulation at their time, neither in Islamic nor in  neighbouring lands, except that it is said that paper money was known and  widespread in 
China – this would explain the view that the  jurists of India were the first to discuss paper money.
For later  jurists, their rulings on zakat, trade and exchange of paper money were based on  their conception of its nature.
This led to 
four different views.
VIEWPOINT 1: PAPER MONEY IS AN IOU  FROM THE ISSUER, i.e. A RECEIPT OF DEBTThe basis for  this position is:
1. The 
promise to pay the value to the bearer on demand,  printed on paper money.
2. The 
necessity of backing the paper money with gold  and/or silver in the issuer’s reserves.
3. Paper money 
has no intrinsic value, e.g. currency notes  denoting five and ten units are similar in size but very different in  value.
4. The 
issuing authority guarantees the value of paper  money when it is abolished and ceases to be legal tender.
Proponents of  this view included several ‘ulama. The fatwa of the 
Shaykhs of al-Azhar  was based on this viewpoint in  the early years, as shown by several  fatawa in the journal of al-Azhar, Majallah  al-Azhar. Ahmad al-Husaini  gave the fullest justification for this position,  making the following  points:
1. There is no meaning to the promise to pay  if paper money is the actual currency.
2. “
Banknote” is a French term and means, according to  the Larousse Lexicon, 
“Paper  currency that is used as mineral currency is used;  it can be exchanged  for its cash value, and must be guaranteed so that people  have trust  in it.”
3. 
Gold is sought after in every time and in every  place, unlike copper.
CorollariesThis viewpoint 
leads to rulings that are difficult and contrived,  e.g.
a) Paper money 
cannot be used for advance payment (bay’ salam)   since one condition of bay’ salam agreed upon by the ‘ulama is that  one of the  parties must take possession of its side of the transaction  (goods, commodities,  money, etc.) at the place of transaction (majlis  al-‘aqd). Paper money would not  satisfy this, since it 
would only be hawalah (referral of a debt), not being  cash in itself.
b) Paper money 
cannot be exchanged for gold and silver even if  this is done on the spot, 
since paper money is an IOU for a debt unrelated to the  contract of exchange. One condition of exchange (sarf) is that mutual  exchange be done on the spot.
c) Dealing in paper money is 
equivalent to the referring of debt in transactions  (al-hawalah bi l-mu’atah) to a third party, the issuer of the paper  money. There is disagreement about the soundness of such third-party  transactions. The mashhur position of the 
Shafi’i school is that it is unconditionally  invalid since the condition of verbal offer and acceptance is not met.  However, assuming that third-party transactions are acceptable,
  it is a condition of debt-referral that it should be to one who will fulfil the  debt, due to the hadith of Abu Hurayrah, “
The  delay in payment by a rich person is injustice. If a  debt is referred  to someone who will fulfil it, the referral should be  accepted.” The 
fulfiller  should have the wealth to pay, should  give his word so that he cannot  delay payment, and must be present when the debt  is settled. There is  no doubt that the power and authority of the ruler make him   untrustworthy with respect to his word and presence, for he is able to  delay  payment and refuse to attend the settlement meeting. Therefore, 
the debt-referral is invalid.
d) The  disagreement regarding zakat on debt applies, i.e. is zakat on a  debt obligatory  before or after settlement? According to the latter  view,
  zakat is not obligatory on paper money since the IOU has not been  settled.
e) It is 
invalid to sell goods or precious minerals held in trust  for paper money since the latter 
is  a receipt for an absent debt, and this is a type of 
selling kali’ for kali’, which the Prophet SAWS  forbade.
Critical analysis of this viewpoint1.  It relies on the 
promise to pay, which is no longer valid and has  no reality, being only 
meaningless words.
2. 
Backing by gold and/or silver is not required in  full.  Most issuing authorities who have prior experience or are pioneers,   operate in this way. Other issuing authorities, including all of the 
Islamic world, are following them in this. It is  not necessary for paper money to be backed fully by wealth, for government  guarantee plays a part, too.
3. The “
no  intrinsic value”  argument: money is whatever is generally accepted as the  medium of  exchange, whether its value is intrinsic or extrinsic (or a mixture).   This is supported by the fact that economic thought requires mints to  make the  
value of mineral money greater than its intrinsic  value,  in order to safeguard its life and help avoid forgeries. E.g. one   Saudi pound is worth 40 Saudi riyals by government decree, whereas a  piece of  gold weighing one Saudi pound is worth 35 Saudi riyals. The  difference is  enforced by government. We do not say that the difference  is a 
state debt, so we cannot say that paper money is  state debt, although the government must take care to stabilise its value,  etc.
This is precisely the secret of the validity of paper money, since  its
 value is not intrinsic but guaranteed by  government. This does 
not imply that it is an IOU or debt since it cannot be  redeemed in gold and/or silver.  The IOU viewpoint leads to hardships and  constriction upon the public,  whereas a general principle in the Shari’a is that  in a matter lacking  an unequivocal text, there should be ease upon the people  rather than a  burden.
In a treatise 
arguing that banknotes are equivalent to fulus  (i.e. token currency), Sheikh Ahmad al-Khatib says:
♦ If it is said that  paper money is 
not intrinsically currency,  for its issuer would  otherwise not be obliged to redeem its value, we  answer as follows. Transactions  are intrinsically carried out using  paper money: it is the paper money that is  held, handled, exchanged and  used in buying and selling like all other  currencies. 
The issuer guarantees its value:  this is no reason  not to use it, since without this guarantee, it  would never circulate to begin  with. The cause of its circulation  cannot be a reason to forbid its circulation!  
It is not a debt, but a guarantee of value to ensure  circulation.
♦ 
Value is destroyed if the banknote is destroyed,  
unlike an IOU which is only a reminder, not used in  transactions and has no monetary value except the value of the paper,  etc. The 
debt is not tied to the IOU: the debt is the  responsibility of the debtor. The 
amount written on an IOU is not the value of the IOU, but  a debt for which the debtor is responsible. The 
debt does not disappear if the IOU is destroyed.   Anyone who destroys an IOU (or certificate of ownership of a house,  etc.) only  pays for its price in terms of the paper, ink, etc. as our  jurists have  explicitly stated.
VIEWPOINT 2: PAPER MONEY IS A COMMODITY, AND THEREFORE  CARRIES THE SAME CHARACTERISTICS AND LEGAL RULINGS AS TRADE  COMMODITIESThe basis for this position is:
1. Sheikh  ‘Abd al-Rahman b. Nasir al-Sa’di, in his treatise on the  Ruling on Paper Money  (publ. 1378 H), in the form of a trialogue  amongst proponents of the IOU,  Commodity and Value viewpoints, puts the  Commodity viewpoint in the following  way: 
Our  evidence is as follows – the paper money is  experientially the price  and the commodity, but not equivalent to gold and  silver. Transactions are based on the banknotes. They are not the same as  gold and silver in substance and source, so the 
ruling on riba in exchange does not apply to them,  even though they are equivalent in value to gold and silver, exactly as is the  case with precious jewels and pearls, etc. 
The basic principle in trade is that transactions are  halal; we cannot state that they are haram without decisive proof. The  
view  that paper money is a debt leads to harm and  difficulty: the Shari’ah  makes matters easy for people, and is applicable to  every time and  place. People are in the situation of necessity, for most  of the  world uses paper money. Another piece of evidence that paper money is  not  like gold and silver is that the former’s value is based on 
governmental authority, and this 
value can vanish if the government is replaced or if it  changes its policy. Thus, 
paper money is equivalent to gold and silver  in  trade and matters of monetary worship such as zakat and nisab, but  not the same  as gold and silver in the ruling on riba in exchange since  the mashhur in our  madhhab is that the ‘illah for the riba ruling on  exchanging gold and silver is  that they are weighed, and a banknote  denoting 1,000 units may weigh the same as  one denoting 100 units.
2. Sheikh Yahya Aman, a proponent of the “
commodity viewpoint” said in treatises published  in 1378 that paper money is 
valuable wealth, which people store for their  needs. This is the
 meaning of wealth (mal):  human nature inclines  towards it, and it can be stored for occasions  of need. The possessor of paper  money takes ownership of it by giving  dirhams or riyals. The paper money is  regarded as wealth and treasured  (like gold, silver and fulus), stored, gifted,  bequeathed in wills and  given in charity. People’s understanding and intentions  are only that  it is to be bought and sold: actions are by intentions. Therefore,  
paper money is wealth (i.e. a  commodity).
3. Sheikh Ali Hindi quotes a fatwa from Sheikh  Sulayman b. Hamdan, publ. 1378, as follows. 
Paper  money is equivalent to trade commodities (goods),  for the definition  of trade commodities is that these are neither measured by  volume or  weight, nor are they animals or property. Commodities are   valuable items, and paper money comprises items that have effective  value on the  basis of governmental authority. The names printed on the  notes, e.g. riyal,  dinar and pound, are metaphorical (majazi) since one  can negate these names,  e.g. by saying that this note is not a riyal  of silver, a pound of gold, etc.  Legal rulings in Shari’ah cannot be  based on meaningless names divorced from  reality, especially in matters  of halal and haram.
Summary of this  viewpoint1. 
Paper money is desirable, valuable wealth. It is  treasured and used for buying and selling. It is 
not similar to gold and silver in substance and  source.
2. Paper money is 
not measured by volume or weight, and therefore  
does not fall under any of the six categories of items on  which the ruling of riba applies in exchange.
3. The 
names of the currencies are metaphorical: the  reality is that the paper money is 
valuable wealth.
4. Paper money is 
not equivalent to gold and silver in type and  measure: paper is 
not a precious mineral; paper money is 
not weighed, unlike gold and  silver.
Corollaries of this viewpointa) 
Bay’ salam is not allowed using paper money,  according to the viewpoint that one counter-value in 
bay’ salam must be gold or silver.
b) 
Riba of both types does not apply to paper money:  one is allowed to exchange different quantities of it with gold and silver,  on-the-spot or with deferred payment.
c) 
Zakat is not payable on paper money unless it is  set aside for sale.
Critical analysis of this viewpointThe  IOU and commodity viewpoints represent two extremes that 
open the door to riba and nullify most forms of  zakat. E.g. A million pounds deposited upon a return of 8% interest would 
neither fall under riba nor be liable for zakat!   People need to be deterred from the corruption and materialism of our  time, not  encouraged! Paper money is not the same as paper that is used  for writing and  packaging, etc. Sound qiyas is binding in Shari’ah:  the correct ‘illah of riba  in the exchange of gold and silver is that  they are a measure of value, not  their substance, source or  weighability. As for the argument that paper money  names are  metaphorical not real, 
Sheikh  ‘Abdullah b. Bassam has answered this in his fatwa  of 1378 by saying  that there are three types of realities: linguistic, legal and   customary. Paper money has a customary reality (haqiqah ‘urfiyyah) since  it is  customarily a measure of value.
Thus, p
aper  money has the same ‘illah as gold and silver:  thamaniyyah (a measure  of value or “moneyness”), but it is of a different  type. Therefore, the ruling on exchanging paper money for gold and silver  is from the hadith, “
Exchange them as you wish, as long as it is hand-to-hand  (i.e. on the spot).”
VIEWPOINT 3: PAPER MONEY IS THE SAME AS  FULUSThis viewpoint is a moderate one between the IOU and  commodity viewpoints. 
Fulus does not necessarily have to be made of  copper, although it has been ever since the Arabs took the idea from the  Byzantines. 
The  Byzantine value and coinage of fulus was unstable,  and the Arabs  stabilised it: the copper coin weighed 0.194g, and 48 coins  equalled  one dirham in value. Proponents of this view and their arguments  include:
1. Sheikh Ahmad al-Khatib: 
No  zakat is to be paid on paper money unless it is set aside for sale, since  
paper money is the same as fulus. 
No  riba applies on paper money: one can exchange it in equal or unequal  quantities, on-the-spot or with deferred payment.
2. Sheikh Abdurrahman  al-Sa’di: This viewpoint is a 
moderate  one between the commodity view and the  view that “paper money is  equivalent to gold and silver,” and is the best way to  reconcile the  various legal evidence. Thus, 
paper money is equivalent to gold and silver in deferred  transactions, so one cannot exchange 10 units for 12 units later, but  
equivalent to fulus in spot-transactions, so one  can exchange whatever quantity one likes on the spot. This is the best view in  the situation of need (hajah), for p
aper money is not the same as gold and silver in  reality, and this view is based on the objectives of the Shari’ah without  opposing its texts. 
Many ‘ulama allowed the spot-exchange of fulus with gold  and silver in equal or unequal value, but not with deferred payment. This  is true even though 
fulus is closer to gold and silver than paper  money.  Riba al-fadl is haram because it is a means to riba al-nasi’ah,  and  even fadl (exchange of unequal countervalues) is allowed out of  necessity,  e.g. the sale of ‘araya. Many ‘ulama including  Sheikh-ul-Islam Ibn Taymiyyah  allowed the sale of gold and silver  jewellery for equal or unequal quantities of  gold and silver coins or  jewellery, considering the value and price of the  jeweller’s  labour. Because of today’s need (hajah) or even necessity (darurah),  
the  fact that paper money is not the same as gold and  silver and that we  allow unequal exchange only on the spot, plus the  disagreement of the  ‘ulama about the ruling on paper money: all of these factors  strengthen  this view over all others.
3. Sheikh ‘Abdullah b.  Bassam: 
Paper money resembles gold and silver in some respects  and resembles IOUs or debt-receipts in other respects. However, its 
strongest resemblance is with fulus coinage such  as nickel. Paper money is 
not intrinsically like gold and silver: its value  fluctuates, just like fulus, due to supply, demand, circulation and  governmental decree. Gold and silver are intrinsically desirable; 
paper money and fulus or qurush are only desirable due to  government decree. Therefore,
  paper money is to be treated like fulus or qurush.  The correct position  in the madhhab of Imam Ahmad is that riba  al-nasi’ah applies to qurush (i.e.  exchange cannot take place with  deferred payment) but riba al-fadl does not  (i.e. unequal exchange can  take place, but only on-the-spot).
Corollariesa)  Paper money is 
not the same as gold and silver, but treated like  fulus.
b) In the view of Ahmad al-Khatib, 
neither riba al-fadl nor riba al-nasi’ah apply to paper  money.
c) In the view of others, 
riba al-nasi’ah applies to paper money, but not riba  al-fadl.
Critical analysisAhmad al-Khatib’s view is wrong, since it nullifies the  possibility of zakat and riba in the case of paper money,  as we have  already discussed. The view of the others is closer to the  truth in our view.  However, it can be criticised on the grounds that  the differentiation in the  ruling between riba al-fadl and riba  al-nasi’ah needs logical or textual  evidence. If they answer by saying  that fulus has two roles: (i) as a commodity  in its substance and (ii)  as a measure of value by government decree, then we  answer by saying  that in matters where there is a
  mixture of two situations, 
the  most cautious approach is taken in order to preserve  the five legal  necessities: religion, life, intellect, progeny and  wealth.
An example of this is the hadith transmitted by the five  authorities  (Bukhari, Muslim, Abu Dawud, Nasa’i and Ibn Majah) on the authority  of  ‘Aishah that Sa’d b. Abi Waqqas and ‘Abd b. Zam’ah referred their  dispute to  the Messenger of Allah (SAWS). [Sa’d’s brother ‘Utbah had  had an 
illegitimate son  by the slave-girl of Zam’ah, the  father of ‘Abd.] Sa’d claimed that  the person was his nephew and should be given  to him, for ‘Utbah had  entrusted him thus. ‘Abd claimed that the person was his  half-brother,  for the latter was born on his father’s bed. The Messenger of  Allah  (SAWS) saw the resemblance between the person and ‘Utbah and said, “
He   is yours, O ‘Abd b. Zam’ah: the child is attributed to the bed on  which it is  born, and the adulterer is stoned. O Sawdah bt. Zam’ah,  veil yourself from  him!” The person never saw Sawdah. Thus, the  Prophet (SAWS) attributed  the person to the bed where he was born,  following the basic principle of the  legal father. However, he also  attributed the person to another for the mahram  rule out of caution,  after seeing the obvious resemblance with his biological  father. 
This  combination of two rulings was done in such a way  that no prohibited  matter would be violated; extra care was taken to safeguard  progeny  (lineage), one of the five legal necessities.
This  is very different to allowing riba al-fadl in the  case of fulus, a  matter that will open the door to riba, since riba al-fadl is a  means  towards riba al-nasi’ah. Further, there are important 
differences between paper money and fulus,  illustrating that the former should be given the same ruling as gold and  silver:
1. 
Paper money is used for no other purpose than as a  measure of value, unlike 
fulus that can be traded as a commodity in view of its  substance.
2. When 
ordinary paper is converted into paper money, it loses  its original nature, 
unlike the case of fulus. 
(7)3. In  value, 
fulus is much less than gold and silver whereas  
paper money reaches the same value as gold and  silver. In fact, some banknotes are 
worth far more than any gold or silver  coin.
4. 
Fulus is generally used in pricing low-value  items, and this is partly why some ‘ulama have allowed riba al-fadl in  the case of fulus.
5. 
Fulus cannot be used in pricing high-value items:  only gold, silver or paper money are used for this. Riba usually occurs in  high-value transactions.
These differences justify treating paper money  on a higher level than fulus, with the corresponding extra rulings and  effects.
Statements of the Jurists: the Legal Rulings regarding  FulusThe jurists have considered fulus and generally fallen  into 
two camps, based on their view of fulus as (i) the  
original substance from which it is made, or (ii)  its 
role as money and a measure of value.  Based on  these viewpoints, the jurists differentiated fulus from gold  and silver, or  equated it with them, respectively. Further, they  respectively did not or did  give fulus the same legal ruling as gold  and silver in matters of riba, sarf,  salam and zakat.
The First View: Fulus is different from gold and silver, and  therefore 
does not share the same rulings regarding riba, sarf,  salam and zakat.
1. The author of Sharh al-Muntaha (Hanbali law,  vol. 2 p. 194) says, “
Riba  does not apply to fulus that is used by number, even  if it is used for  spending (nafiqah), for it is not measured by volume or weight  and  because of the absence of an unequivocal legal text (nass) and legal   consensus (ijma’).”
2. “
It   is allowed to sell one fils for two in number, even if they are used  for  spending (nafiqah) because they are not measured by volume or  weight.”  Kashshaf al-Qana’ ‘ala Matn al-Iqna’, Chapter on Riba and Sarf, vol. 3 p. 206  (Hanbali)
3. “
Gold  and silver are the measures of value (thaman), so it  [zakat on cash]  does not apply to fulus, even if it is in general  circulation.” (ibid., vol. 2 p. 205, section – Zakat on Cash)
4.  “
Fulus  are like trade commodities: zakat is due on their  value and the zakat  cannot be paid from them, just like all other trade  goods. (8) If  the fulus is for spending, there is no zakat due upon it, just like perishable  goods.” (ibid., vol. 2 p. 212, section – Zakat on Jewellery)
5.  “
Riba does not apply to fulus, even if it is in  circulation.” (Sharh al-Bahjah al-Kabir – Shafi’i law)
6. “
Riba  only applies to the types of cash: gold and silver,  even if they are  unminted, such as jewellery and bullion, as opposed to trade  goods and  fulus, even if these are in circulation.” (Sharh al-Manhaj by  Sheikh Zakariyya al-Shafi’i)
7. Sheikh ‘Iliyyish al-Maliki says in Fath  al-‘Ali al-Malik ‘ala  Madhhab al-Imam Malik, in a fatwa about zakat on paper  money, “
There  is no zakat on copper fulus, minted by the ruler  and in circulation …  In the Mudawwanah, it is narrated that Malik was asked  about a man who  possessed fulus worth 200 dirhams upon which a year passed. He  said  that no zakat was due upon it.”
8. “Z
akat is limited to gold and silver: there is no zakat due  on copper fulus. This is the [Maliki] madhhab.” (Dirdir’s commentary on  Mukhtasar Khalil)
9. Imam Abu Hanifah said that 
if  a person bought fulus for dirhams and one of the parties paid whilst the other  deferred payment, this was permissible. However, if 
both parties deferred payment, this was not permissible  because it was a debt for a debt.  If a person bought a gold or silver  ring with fulus to be paid later,  this was permissible. (Fatawa Hindiyyah,  Hanafi law, quoting from  Al-Muhit and Al-Mabsut respectively for the two  situations.)
10. “
It  is permissible to sell one fils for two or more.”  (Muhammad ‘Ala’ al-Din,  al-Durr al-Mukhtar, Hanafi law) The commentary  by Ibn ‘Abidin says that this is  permitted by Abu Hanifah and Abu  Yusuf because they are not intrinsically money  (athman) and are  therefore treated like commodities. (Radd  al-Muhtar)
The  Second View: Fulus is similar to gold and silver, and therefore  
shares the same rulings regarding riba, sarf, salam and  zakat.
1. “
Fulus  in circulation is money (athman). This view is  amongst those on the  authority of Imam Ahmad … Ahmad said, ‘One fils must not be  sold for  two’ … There are two opposing narrations from Ahmad on this matter. In   al-Talkhis, the matter was left undecided. One of the narrations is that  unequal  exchange is not allowed, and this is transmitted by a group of  Ahmad’s students.  It is the view preferred in al-Mustaw’ib and al-Hawi  al-Kabir.” (Abu  l-Khattab, Tashih al-Furu’, Hanbali law)
2. “
For  the exchange of fulus in circulation for cash [i.e.  gold and/or  silver], the conditions of spot-transaction (hulul) and taking  delivery  of payment (qabd) apply.” (Rawd al-Murbi’ Sharh Zad  al-Mustaqni’, Hanbali law)
3. Ibn al-Qayyim has a valuable discussion on  the matter of the ‘illah  of riba in gold and silver in his I’lam al-Muwaqqi’in,  in which he 
criticises those who treated fulus as trade goods.  E.g. he says, “
I  saw the corruption of their dealings and the harm  caused by them when  fulus were treated as a commodity to be sold for profit.  There was  widespread harm and much injustice. If fulus were to be treated as a   single currency (thaman) of stable value, by which other things’ value  was  measured and not vice-versa, public affairs would be set aright.” (vol. 2  p. 137, Hanbali law)
4. Ibn Taymiyyah was asked about the 
permissibility  of fulus being bought for a specified  amount of cash (i.e. gold and/or  silver) and sold for profit with deferred  payment. He replied, “
In   this matter, there is a well-known dispute amongst the people of  knowledge, i.e.  the exchange of fulus in circulation for dirhams: is  the spot-transaction a  condition, or is deferred payment allowed? They  take two well-known views that  are both found in the Madhhabs of Abu  Hanifah and Ahmad b. Hanbal. One of these  views, the one mostly related  from Ahmad as well as being the view of Malik and  one of the views  transmitted from Abu Hanifah, is that it is not permissible;  however,  Malik said that it was not clearly prohibited. The second view is that   of Shafi’i, Abu Hanifah in the other transmission and the narration of  Ibn ‘Aqil  from Ahmad is that it is permissible. Some of the ‘ulama take  Ahmad’s  forbiddance to mean a dislike, for he said, ‘It resembles  exchange.’ The  stronger position is to forbid this, for fulus in  circulation is mostly regarded  as money (athman) and is made a measure  of the value of people’s wealth. …  Establishing the ‘illah as moneyness  (thamaniyyah) is to use an appropriate  ‘illah, for the objective of  money (athman) is to be a measure of the value of  wealth, rather than  to be benefited by it in itself. Thus, if some of it is sold  for other  of it with deferred payment, the objective becomes trade, which   contradicts the purpose of moneyness. The conditions of spot-transaction  and  delivery of payment are to complete this objective. … The Lawgiver  has thus  forbidden that money (thaman) should be sold for money with  deferred payment.  Since fulus has become money, the same ruling applies  to it: money must not be  sold for money at a later time.” (Fatawa Ibn Taymiyyah, vol. 29 pp.  468-471, Hanbali law)
5. Ibn al-Qasim said: I asked Malik about
  fulus that was sold for dinars and dirhams with deferred payment, and about the  sale of one fils for two. He replied, “
I  dislike that, as I dislike it for gold and silver.” (Al-Mudawwanah  al-Kubra, Kitab al-Zakat, Maliki law)
6. Ibn al-Qasim said: Malik said to  me about fulus, “
There  is no goodness in exchanging these for gold or  silver with deferred  payment. If the people were to agree amongst themselves on  using skins  (as money) such that these were made into coins and monetary units,  I  would dislike these to be sold for gold and silver with deferred   payment.” Malik also said, “
It  is not allowed to sell one fils for two.” (ibid., Kitab  al-Sarf)
7. Sheikh Muhammad ‘Ali b. al-Husayn, in his fatwa about the  ruling on  paper money (pp. 57-8), quotes from al-Mudawwanah al-Kubra as follows,  “
If  someone buys fulus with a coin or ring of gold or  silver and the two  parties separate without both of them taking delivery of the   countervalues, this is not allowed. This is because there is no goodness  in  exchanging fulus for gold or silver with deferred payment. Malik  said, ‘It is  not clearly prohibited, but I dislike the delay in  payment.’ … This is not  allowed, except in equal number: one fils for  another, hand-to-hand. It is not  valid to sell one fils for two,  neither hand-to-hand nor at a later time. Fulus  in number are like  dirhams and dinars in weight. … Brass and copper are  commodities as  long as they are not minted into coins. Once they are minted as  fulus,  they are treated just like gold and silver in matters of halal and haram   and exchange (sarf).”
Al-‘Adawi says in his margin to Khirashi’s  commentary on Mukhtasar Khalil, “
Malik’s dislike here is to be regarded as such  (literally), not as prohibition.”  However, this is dubious since Imam  Malik expressed the same dislike  regarding the prohibition of the unequal  exchange of gold and silver by  saying, “
I  dislike that, as I dislike it for gold and silver.”
Ibn al-Qayyim  quotes in his I’lam al-Muwaqqi’in from Ibn Wahb: I heard Malik saying, “
It   was not the way of the people, nor of those who preceded us, nor did I  ever come  across people worth of being followed, saying about any  matter, ‘This is halal  and this is haram.’ They would not dare to say  that. Rather, they would only  say, ‘We dislike this,’ or ‘We regard  this as good,’ or ‘This is fitting,’ or  ‘We do not take this view’.”
‘Atiq b. Ya’qub also narrated this  from Imam Malik; this transmission adds, “
They  would not say, ‘halal’ or ‘haram.’ Have you not  heard the saying of  Allah the Exalted, ‘Say: Do you see the sustenance that  Allah has sent  down for you, that you make some of it unlawful or lawful? Say:  Has  Allah granted you permission, or do you invent lies against  Allah?” 
(9) The  lawful is what Allah and His Messenger  have made lawful, and the  prohibited is what Allah and His Messenger have  prohibited.
Ibn al-Qayyim commented on the above statements of Imam Malik  by saying, “
Many  of the later followers of the Imams have mistakenly  attributed matters  to their Imams because of this cautious reluctance of the  Imams to use  the word ‘haram’ unreservedly. Thus, the later followers denied the   prohibition of matters for which the Imams used the word, ‘dislike.’  Next, the  word ‘dislike’ became easy for them and its seriousness  lessened for them: some  of them took it to mean ‘light dislike’  (tanzih); others went even further,  taking it to mean ‘the dislike of  leaving what is better’ (tark al-awla). This  occurs extremely often in  their expressions and because of it, a grave  misunderstanding of the  Shari’ah and the Imams has arisen.”
8.  Sheikh Muhammad ‘Ali b. Husayn quotes from the Hidayah (Hanafi law) as follows,  “
It  is not allowed to sell fulus for gold or silver with  delayed payment,  because our jurists have said explicitly that a weighable  cannot be  advanced in payment for another weighable. The only exception is when   the weighable for which the sum is advanced is saleable, such as saffron  etc.  Fulus are not saleable goods: rather, they have become money. …  The fatwa is  that zakat is obligatory on fulus that is in circulation  when its value reaches  200 dirhams of silver or 20 mithqals of gold.”
9. Imam Muhammad b.  al-Hasan took a view contrary to his two companions (Abu Hanifah and Abu Yusuf),  
viewing  fulus in circulation just like money (i.e. gold  and silver), with all  the necessary legal enforcements and prohibitions that  this entails,  such as zakat and riba. This is confirmed by al-Kasani in  his Badai’ al-Sanai’ (vol. 5, p. 185, Hanafi law), and others.
ConclusionFrom  the preceding discussion, it is clear that 
most jurists have treated fulus as a trade  commodity, but that 
those who have carried out critical analysis (the  muhaqqiqin) have said that fulus is treated just like money. In my view,  there is no doubt that those who say that fulus in circulation is just like gold  and silver have a 
deeper understanding  and stronger argument. The  real world also supports their view, for  fulus is money that is  generally-accepted amongst the public as a  medium of exchange just like gold and  silver. T
rading in fulus when in circulation has the same effects  as trading in gold and silver. The 
view that fulus is a trade commodity is nothing but a  literalist view, clearly distant from the spirit and secrets of the  Law.
VIEWPOINT 4: THE “SUBSTITUTE”  VIEWAccording to this view, 
paper money is a substitute for gold and silver, and the  substitute has the same ruling as the substituted. It has the same  moneyness as the gold and silver on which it is based and by which it is backed.  The
 Shari’ah is based on objectives and meanings, not mere  words and labels. This view is supported by the fact that 
if  the paper money loses its status as money, it reverts to being worthless  paper.
Corollariesa) Both types of 
riba, fadl and nasi’ah, apply to paper  money.
b) 
Zakat is obligatory when paper money reaches the nisab  amount of gold or silver, depending on its basis.
c) Paper money  
may be used in bay’ salam.d) 
Paper money has the same legal rulings as gold or  silver, depending on the precious metal upon which it is based.
e)  
Unequal exchange of two paper currencies based on the  same precious metal is not allowed.  E.g. Saudi riyals and Lebanese pounds  may only be exchanged on the  spot for the same value (in silver); similar is the  case with Kuwaiti  dinars and pounds Sterling (gold).
f) 
Unequal exchange of two paper currencies based on  different precious metals is allowed, as long as this is done on the  spot.
Critical  AnalysisThis viewpoint is the 
closest to the truth (10), except that as  we saw in Chapter Four, paper money has passed through several stages until it  
gained the confidence of the public, who no longer asked  about its backing.  Thus, the issuing authorities saw that they did not  need 100% backing –  only an acceptable percentage of the paper money was  backed;
 the rest could be regarded as promissory notes,  in the sense that the issuing authority was required to 
guarantee their value. Furthermore, 
backing did not need to be with gold and silver –  it could be done with property (e.g. Germany) or treasury bills.
This  
viewpoint is based on paper money being fully-backed by  gold and/or silver. The 
real-world reality is different, however, for the  backing for paper money comes from state enforcement and public acceptance.  Therefore, this 
viewpoint needs support from the real  world.
CHAPTERS  SIX AND SEVEN: THE ‘ILLAH OF RIBA IN THE EXCHANGE OF GOLD AND SILVER, AND THE  WISDOM BEHIND THISConclusion: After  numerous quotes from  Ghazzali, Ibn Taymiyyah, Ibn al-Qayyim, Ibn  Hajar, etc.: the ‘illah is  thamaniyyah (moneyness), and the wisdom is  that the 
money is used for its purpose as a medium of exchange,  measure of value and store of wealth, and not traded like a  commodity.
CHAPTER  EIGHT: THE PREFERRED VIEW ON THE REALITY OF PAPER MONEYPaper money 
has no intrinsic value, but 
has an extrinsic value that is based on the  following factors, amongst others:
1. The 
economic situation of the state.
2. 
Public confidence in paper money as a trustworthy  store of value and in its unrestricted buying power.
3. State enforcement  of paper money as 
legal tender.
The preferred view  is:Paper money is an independent type of money (thaman),  similar to gold, silver and other mineral money. Paper currencies from  different issuing authorities are different types of money.
CorollariesSome  of the corollaries of this view are:
a) 
Both types of riba, fadl and nasi’ah, apply to paper  money  as they do to gold and silver, and to other forms of money such as   fulus, according to the correct view amongst the ‘ulama. This implies   that:
(i) 
Paper currencies cannot be exchanged for each other with  deferred payment, under any circumstances.
(ii) 
Unequal amounts of the same currency may not be  exchanged, whether on the spot or with deferred payment.
(iii)  
Different paper currencies may be exchanged in any agreed  ratio, as long as this is done on the spot.
b) 
Zakat is obligatory on paper money if it reaches the  lower nisab of gold or silver.  This applies if the nisab is reached in  one currency only or in a  mixture of different currencies, or a mixture of paper  money and trade  goods.
c) It is 
allowed to use paper money as capital in bay’ salam and  partnership (musharakah).
APPENDICESAPPENDIX ONE: FATWA OF THE COUNCIL  OF SENIOR ‘ULAMA OF SAUDI ARABIADated Rabi’ al-Thani, 1393  (c. 1973)
The conclusion of the fatwa is exactly the same as the  “corollaries” in  Chapter Eight of this book. The fatwa was passed after three  sessions  of deliberation between 1/4/1393 and 17/4/1393 that included questions   and answers with Dr. Anwar Ali of SAMA and Dr. Umer Chapra, the   economist.

(12)OtherA different view, recorded with the  fatwa, was taken by:
‘Abdul Razzaq ‘Afifi, 16/4/1393: The currency needs  to be backed in  principle by the resources of the country. It is not necessary  that  there be physical reserves of gold or silver, etc., as long as there are   enough resources available within the country to produce items that  have  equivalent value of the gold, silver or other previous money.  Questions were  asked of the economic experts about backing of paper  money, reasons for the  fluctuations in currency values, whether the  currency was an independent form of  money or a substitute for another,  etc. Some members of the council had further  questions to ask that were  dependent on the answers to the earlier questions.  However, not all  questions were taken, perhaps because of the shortage of time  (although  further sessions could have been called) or because of most members’   sufficing with the answers to some of the questions.
APPENDIX TWO: TEXT OF THE  DECLARATION OF THE ISLAMIC FIQH ACADEMY, 5TH SESSIONHeld at  the HQ of the Muslim World League, Makkah al-Mukarramah, between the 8th and  16th of Rabi’ al-Thani, 1402
The basis of money is gold and silver. The  most correct view regarding  the ‘illah of riba in them is that it is thamaniyyah  (moneyness).
The remainder of the declaration is very similar to the  preceding fatwa.

APPENDIX THREE: LETTER OF ENDORSEMENT FROM MUSTAFA AHMAD  AL-ZARQA’Dated 29th Shawwal 1392 / 4th December 1972
A  letter of praise and thanks for the work of Ibn Mani’. Enclosed with  the letter  was al-Zarqa’s treatise on the Islamic ruling on insurance  contracts. There were  also suggestions regarding some of the points  mentioned in the text of the book,  and Ibn Mani’s replies to these.
FOOTNOTESource: http://muslimvillages.com1 [UH:] There is a fourth property of money in  conventional economics:4. A standard for deferred payments.The following rhyme summarises these four  properties:Money is a matter of functions four:A medium, a measure, a standard, a store.I am grateful to Prof. Khurshid Ahmad for teaching me  this rhyme!2  [UH:] Tarek Diwany comments: This version of the  history of money is  especially by the banks, since it usually fits their  purpose. However,  there is an alternative view: since Adam (a.s.) was taught the  names of  everything, would he not have been taught the name, and therefore the   nature, of money? In fact, there is a narration in which Ka’b al-Ahbar  says that  the first person to mint the dinar was Adam a.s., the first  man. Allah knows  best.3  [UH:] Marco Polo says in his travelogue of China, “The  people of China  only buy and sell using pieces of paper, about the size of a  person’s  palm, stamped with the seal of the king. If the pieces of paper become   torn, they are taken to a place resembling a mint where they are  replaced with  new pieces of paper without anything else being demanded  in return. If a person  goes to the market with silver or gold coins in  order to buy something, these  are not accepted from him and no-one even  looks at him until he exchanges them  for the paper money, upon which  he can buy whatever he wishes.”4  [UH:] An interesting chapter, especially the quote from  Marco Polo,  although the extent of material backing of the paper money is not  clear  from this quote. [TD:] The paper money in China was in use for several   centuries, with its value based purely on state enforcement. In fact,  within  about a century of the Kublai Khan prohibiting the use of gold  and silver, China  experienced hyper-inflation and its economy was  seriously weakened. Were the two  events related? Whatever the case, the  weakening of the economy aided the  British economic forays into China.5  [UH:] The preceding two chapters allude to fractional  reserve banking.  However, the author does not mention the growth in usurious   money-lending that accompanied the spread of paper money, as first the   goldsmiths and then the banks not only issued unbacked paper money, but  lent it  out at high rates of interest. This is a crucial matter that  must be brought to  the attention of the Shari’ah scholars, for fatwas  on the legality or otherwise  of fractional reserve banking, and Allah  knows best.6  [UH:] The views and practice of pro-usury economists  and politicians  would not appear to be a sufficient argument in Shari’ah. An  Islamic  legal ruling on fractional-reserve banking would be useful. It appears   from the words of Sheikh ‘Afifi (see Appendix One) that the scholars  would  demand the full backing of state-issued currency, although this  backing could be  potential rather than actualised, e.g. the state would  not necessarily need  physical reserves of gold and silver etc. to  issue paper money, as long as it  was reasonably sure that it had the  resources and means of production necessary  to support its currency.  However, further clarification of this matter from the  viewpoint of  Shari’ah would be extremely useful.7  [UH:] This seems to be a weak argument. During the  German  hyper-inflation experience of the 1920s, already mentioned twice by the   author, some people did indeed collect stacks of the now-worthless  paper money  (the mark) and sell it as paper, the original substance.  However, this does not  significantly weaken the overall point being  made by the author.8  [UH:] This is similar to the Murabitun’s position  regarding the paying  of zakat on paper money, except that they do not stipulate  that it  should be for sale, i.e. like trade goods. They treat paper money like   gold and silver in being zakatable, but treat it like fulus in that the  zakat on  it must be paid in gold and/or silver.9 [UH:] Surah Yunus, 10:5910  [UH:] i.e. of the four viewpoints described in this  chapter. See  Chapter Eight for the author’s preferred view on the nature of  paper  money.11  [UH:] The Sheikh al-Shinqiti of Chinquette  (Mauritania) was perhaps  the most senior, most learned and most traditional of  the ‘ulama on the  council. He passed away a few months after these sittings, may  Allah  have mercy upon him. It is an intriguing question as to what his  position  was on the matter, and why he abstained from endorsing this  fatwa. Allah knows  best.12 [UH:] This scholar later endorsed the fatwa – see  Appendix Two.13  [UH:] Note that this jurist abstained from the fatwa  of the Saudi  council nine years earlier, but later agreed with the same view  when it  was adopted by the Islamic Fiqh Academy.
