In principle, an economic system is concerned with the process of production and consumption of goods and services, while the political economy provides it with the proper political framework. The monetary system is not necessarily a part of the economic system. Money is a tool used to measure the value of goods and services during the production and consumption processes. This measure is required during the exchange of products and benefits between the producers and consumers. Ancient groups of peoples (tribes and primitives societies) were able to produce all the goods they needed to live and survive, and hence did not require a standard measure for the values of their goods and services. Money, therefore, was not part of the system of production and consumption.

The progress and advancement of societies created the need for people to exchange goods and services within the same society as well as across societies. Initially, the trade of goods and services was conducted using barter methods through the exchange of goods for goods, goods for services, or services for services. One such example reported in the Quran is when Prophet Moses (PBUH) paid eight years of services in exchange for marrying the daughter of his employer, Prophet Shuaib (PBUH).135 The exchange of goods and services for a specific unit of exchange, called money, was introduced in the period 600-650 BC.136 Money came to be a standard measure for the benefit found in goods and services. However, money did not replace barter exchange methods but provided a new method. Therefore, money is defined as the medium by which goods and services are measured. The capitalists called the value of goods and services “price” when this value is measured by money. So the price under capitalism is another name for the exchange value of goods and services. Under Islam, the price given in money is not an intrinsic value of things; rather it is an estimate of that value.

The price of a commodity and the wage of a worker, for instance, each represent the society’s estimate of the value of that commodity and the effort of that worker. This estimation of the value of goods and services is expressed by well-defined units. These units become the measure by which the benefit obtained from a commodity and the benefit obtained from a service is measured. These units would act as a medium of exchange, and these units are money.

Islam approved barterlike method as well as money for conducting trade transactions. People are allowed to choose either method for the exchange of goods and services based on mutual agreement and the best interest of the trading parties. Either way, using barter or money, the price of the goods or services has to be explicitly defined in the process of exchange. For example, a person can purchase a horse in exchange for working a week in the horse stable of the seller, given that the number of hours of work per day is well defined, or he can pay an ounce of gold for the horse.

Islam did not leave the monetary system undefined; rather it specified the gold and silver as the base units for the monetary system. Both gold and silver were extensively used by societies and civilizations before Islam due to the intrinsic value of these precious metals. The Roman Empire used gold as the main currency and struck several gold-based units at a well-defined shape and weight; one of these units was the “denarius” or the dinar, which was the main coin issued by republican and imperial Rome. The gold dinar was used throughout the Roman Empire and its satellite states.

The Persian empire used silver as its main currency and issued three types of silver coins, called dirham, with different shapes and weights. The Arab tribe of Quraish, where Mohammad the Prophet was born, did not have a currency of its own; rather Quraish used the Roman gold dinar and Persian silver dirham, which they received in exchange of their merchandise. The Arabs used the weight of the gold and silver coins as units of exchange instead of the number of coins.

After the rise of Islam, Mohammad (PBUH) approved the use of gold dinar and silver dirham as was used by the Arabs in Mecca. He also approved the weight of the gold dinar which was the standard weight used by the Quraish merchants in Mecca. It is narrated that Mohammad (PBUH) said, “The weight (of the gold Dinar) is the same as the weight used in Mecca.”137 The Islamic consideration of gold and silver as a base for currency is further evident in the following cases:

1. When Islam prohibited the hoarding of wealth, it only prohibited the hoarding of gold and silver despite the fact that wealth includes any property that can be owned. Wealth includes money (gold and silver), land, cattle, grains, and much more. However, hoarding applies only to monetary wealth; it does not apply to other forms of wealth. It is possible for people to stash away certain goods and commodities such as food items, but this act falls under the term monopoly rather than hoarding, which aims at raising the prices of goods. The prohibition of monopoly is referenced in other places in the Quran and Sunnah. It is the hoarding of money alone which interrupts the production cycle of goods. Therefore, prohibiting the hoarding of gold and silver is an indirect reference to the fact that gold and silver constitute the monetary currency in the Islamic state. Hence the verse which prohibits the hoarding of gold and silver in fact refers to the hoarding of money and established gold and silver as the money base.

[9:34] And those who hoard gold and silver and do not spend them in the way of Allah, let them know that a severe punishment is awaiting them.

2. Islam has linked gold and silver to a set of rules which involve monetary transactions. For example, Islam named a specific amount of gold as a fine to be paid in lieu of a killing by mistake (known as Diyyah or blood money). Messenger of Allah was reported to have said, “The blood money for one soul would be 100 camels . . . and for those who deal in gold is 1000 Dinars.”138 Other fines were estimated in terms of gold and/or silver as well. The minimum amount of stolen wealth which invokes the punitive rule of hand amputation is also estimated in gold. Al-Bukhari reported on the authority of Aisha that the Messenger of Allah said, “The hand is cut for the theft of one-quarter (gold) dinar and up The attachment of certain financial rules with the dinar and the dirham makes the dinar with its weight in gold, and the dirham with its weight in silver, the monetary unit by which the values of goods and services are measured. This monetary unit constitutes the base for the money currency in the Islamic state.

3. The messenger of Allah has determined that gold and silver be used as money, and exclusively made them the monetary measure to evaluate goods and services, and ensured that all transactions be conducted with them as their basis. He also established the units of this money, which were well-known and widespread during the lifetime of the messenger of Allah and they were widely used by all people. It has also been established that the messenger of Allah approved of them. All trade and marriage transactions were conducted in gold and silver, in their quality as money, and this has been documented in numerous Hadeeths of the Prophet. The Messenger of Allah has determined the weight of gold and silver with a specific weight, which was the weight of the people of Mecca. Abu Dawud and An-Nisai reported on the authority of Ibn Umar that the Messenger of Allah said, “The weight should be that of the people of Mecca.” 4. When the Zakah dues on money was decreed, Islam determined the minimum amount of money which qualifies for Zakah in terms of gold and silver. This is another reference to money as being the gold and silver.

5. The rules of currency exchange specified the rules of exchange between gold and silver currencies only; this serves clear evidence that money should be based on gold and silver only. Tirmidhi reported that the Messenger of Allah said, “Trade gold for silver as you wish, but hand to hand (without delay).” Bukhari also reported that the Messenger of Allah said, “Gold for silver would be Riba, unless it was hand to hand (without delay).” A solid base for monetary foundation is essential for the stability of both the financial and economic systems, and thus Islam has laid down the rules for the monetary foundation and did not leave them undefined or subject to the fluctuation of the economic conditions. The Shari’ah laws have always referred to gold and silver whenever the subject matter involved monetary transaction. Consequently, the currency within the Islamic political economy would be gold and silver, or based on gold and silver. The rise of the next Islamic state is expected to witness a decisive return to a more solid and stable gold and silver standard as a base for the financial system.

The gold and silver standard does not exclude other forms of exchange. Products could be exchanged for products and services in a barterlike method. The value of products and services will continue to be estimated based on the benefits inherent in these goods. The gold and silver standard only applies to money and monetary exchange.

The first rise of Islam utilized the use of gold and silver as a base for monetary exchange. During the early days of Islam, the Islamic state under the leadership of Prophet Mohammad (PBUH) used the gold and silver coins produced by the Romans, Persians, and Yemeni dynasties. The Muslims, like the Arabs before Islam, used these coins in terms of their weights rather than numbers. The fact that the Prophet approved their use as such makes the use of gold and silver coins an Islamic rule, although they were in use before Islam. The use of Roman, Persian, and Yemeni coins continued for the first seventy-five years of the rise of the Islamic state, until Caliph Abdul Malik Bin Marwan140 struck new Islamic gold and silver coins. He minted the dinar in gold and the dirham in silver and he used Islamic Arabic script to distinguish the Islamic coins from others. The weight of the dinar was 4.25 grams of gold and the weight of the dirham was 2.98 silver grams. These weights were consistent with the weights of the coins struck by the Romans and Persians and used by the Arabs in Mecca before Islam. The gold and silver standard continued throughout the existence of the Islamic state until it was abolished in 1924 in Istanbul.

Besides the use of gold and silver, the Islamic state also used copper coins for buying and selling negligible low-cost items. However, the copper coins were always convertible to gold dinars or silver dirhams. The point is that Islam allows the use of currency printed in any form (gold, silver, copper, paper, digital tokens) as long as that currency is convertible to gold, i.e., backed by gold. Because the gold and silver standard is a Shari’ah Islamic law, it would be prohibited for the Islamic state to issue paper money which is not completely backed by gold or silver, and it would be prohibited for the state to devalue the paper money against the pre-established gold and silver equivalence. The integrity of the Islamic currency, and hence the confidence in such currency, should serve as a stabilizing force in the Islamic political economy. This should also sustain and increase the trustworthiness of the Islamic financial system, especially since the world had suffered a great deal from currency fluctuations under the dominance of capitalist economy.

Under capitalism, the gold standard had suffered several setbacks even when the world community had agreed on the gold standard at the end of the first and second world wars. Islam considers the use of gold and silver a base for currency, an Islamic rule which cannot be violated by the executives of the state and is not subject for the conditions of the market or the international affairs.

Besides the fact that the gold standard is an Islamically lawful rule, it has several benefits, which if considered, would make the gold standard a viable global standard for the world community at large. Throughout the history of money and up until the First World War, the whole world operated the gold and silver standards. No other standards were known to the world until then. The heavy cost of the war and the imperial colonial world affairs which persisted after the war led to the collapse of the gold standard and the introduction of paper money with no gold or silver backup. Realizing the importance of the gold standard for the financial and economic stability, several European countries and the United States tried in 1933 to restore the gold standard but failed under the heavy pressure of depression. At the end of the Second World War, the United States and Europe and several other nations concurred that a gold standard is essential to the stability of the global economy and hence to world peace and subsequently signed the Bretton Woods Agreement.141

In 1971, the United States unilaterally abrogated the gold standard and forced almost every other nation to stack US dollars instead of gold reserves. Since the seventies, there have been numerous calls for a revamped international system to tackle the problem of unfettered capital flows. However, it wasn’t until late 2008 that this idea began to receive substantial support from leading politicians. On September 26, 2008, French president Nicolas Sarkozy said, “We must rethink the financial system from scratch, as at Bretton Woods.”142 On October 13, 2008, British prime minister Gordon Brown said world leaders must meet to agree to a new economic system: “We must have a new Bretton Woods, building a new international financial architecture for the years ahead.”143 Undoubtedly, the gold standard has numerous benefits for the global community. These benefits include the following:

1. The gold basis necessitates the free circulation, import and export of gold, which leads to monetary, financial, and economic stability.

2. The gold standard ensures the stability of exchange rates between the currencies of various countries (less than 5% variation per Bretton Woods). This stability in turn leads to a boom in international trade, for traders would no longer fear the expansion of foreign trade, with potential loss of money reserve values.

The gold standard prevents the explosion of virtual monetary 3. 4. wealth because central banks and governments would refrain from printing excessive amount of banknotes money. The authorities would fear that if they exceeded limits in issuing banknotes, the demand for gold would increase and they would not be able to meet this demand. Therefore, they would always tend to maintain a reasonable ratio between what they issue in terms of banknotes and gold reserves.

Under gold standard, the movements of money, goods, and labor across countries would become easier due to the fixed exchange rates between currencies of various countries. The constraints imposed by hard currency regulations would disappear, giving rise to a more stable global trade.

In the Islamic economic framework, the price is defined as the society’s estimate of the value of goods, and the wage is defined as the society’s estimate of the value of services. Money, on the other hand, is the medium by which this estimate is expressed. It is the medium which enables people to measure various goods and services and refers them to one common base, thus facilitating the process of making a comparison between various goods and between various services by referring them to one general unit which serves as the general standard. Prices are paid for goods and wages are paid for workers on the basis of this unit, which is money.

The value of money is estimated by its purchasing power, i.e., by how many goods and services a person could buy with one unit of the money. Therefore, the medium by which the society estimates the value of goods and services must have a purchasing power in order to qualify as money, i.e., a power with which any person could acquire goods and services.

This medium must originally have its own intrinsic power, or be dependent on an intrinsic power, i.e., it should itself have a value recognized by the public, in order to be considered as money. This is exactly what grants gold and silver the power to serve as a base for money; gold and silver have intrinsic value which has been recognized by societies throughout the history of man. It has been used as a precious metal, as jewelry for men and women, as collateral items and loan guarantees, and as units of exchange. However, the process of issuing money (units with purchasing power) is not the same for all countries in the world. Some countries may adopt money which possesses intrinsic power (gold and silver) or which depends on an intrinsic power. Other countries may adopt conventional money (nonconvertible), i.e., they agree upon a medium to be considered as money and they give it a buying power by means of legislation or government decree; in this case, the money does not possess a real value on its own.

Countries which operate the gold and silver standard use metallic money, paper money, or both. Metallic money is gold or silver coins minted at a certain weight, shape, and style. For example, in the Islamic state, the dinar is a 4.25 gram gold piece struck in a circular shape with Islamic Arabic script. The dirham is a 2.98 gram silver piece struck in a circular shape with Islamic Arabic script. Fractions of the dinar and dirham (for example one-half dinar, one-fourth dinar) can also be struck and minted in certain shapes and styles. In essence, the dinar (gold) and the dirham (silver) are the two basic units from which all other money coins are derived.

Countries which operate the gold and silver standard, like the Islamic state, can also issue paper money in lieu of the gold and silver. The dinar can be issued in the form of a paper printed in a certain style. Each paper dinar will be matched at the state’s treasury by 4.25 grams of gold. Each paper dirham will also be matched by 2.98 grams of silver. Besides paper money, the state can issue metallic coins made of copper or other cheap metals; by the same token these coins will be matched by an equivalent gold or silver. With the advancement of technology, the state may issue electronic currency, where the currency will be provided in digital form. But in all cases, the money in circulation, whether paper, digital, or coins, will not exceed the gold and silver reserves owned and possessed by the state. This type of paper or digital money is called intrinsic money. The state may prefer this method to issue currency for cost saving and security reasons.

Currency exchange is the process of converting one currency for another. This would be either exchanging one currency for another of the same type, such as the exchange of gold for gold, and silver for silver, or the exchange of one currency type for another one of a different type, such as the exchange of gold for silver or vice versa.

The exchange of currencies which belong to the same type is allowed in Islam under two conditions. First, the exchange has to be for the exact same amount, and second, the exchange has to take place at the same time. The Prophet (PBUH) is reported to have said, “The exchange of gold for gold must be done with equal weight and exact amount; otherwise the difference is Riba (usury).”144 The same rule applies to the exchange of silver coins for silver coins. For example, assume that some person has a one-hundred-gram piece of gold and wants to exchange it for five smaller pieces of gold. This transaction is permitted only if the five smaller pieces of gold have a total weight of one hundred grams. Also, the exchange has to take place at the same time, i.e., the person with the one-hundred-gram piece should hand in his piece at the same time when he receives the five smaller pieces. In other words, it is not allowed to give the large piece and receive the five pieces in installments at different times. Islam considers this transaction illegal and treats it as a form of Riba. This rule is extended to all types of currencies. So, if someone wants to buy dollars with dollars or euros with euros, then the amount of exchange must be the same and the money should be received in full at the time of executing the transaction.

When the exchange occurs between two distinct types of currencies, e.g., gold for silver, or dollar for euro, then the weight or quantity can vary because these are two different types of currencies with different values; but the exchange of money must be completed at the same time when the transaction is executed. If the receipt of any of the exchanged currencies is deferred to a different time, then that would be considered Riba according to Islamic law. The Prophet (PBUH) is reported to have said, “Sell gold for silver the way you wish, hand in hand”145 meaning that the rates can vary but the sale should be instantaneous. This rule extends for all types of currencies; for example, the exchange of dollars for yen, or dinars or euros can take place per the rate of each currency, given that the transaction of sale is completed at the time of exchange.

Islam requires that the exchange of the currencies be completed at one time; as such, it prevented any loss due to potential fluctuation of the rates of one currency in relation to the other. When the transaction is completed at the time of exchange, the negotiated prices for both currencies are guaranteed for both the seller and the buyer. However, if one of the currencies is not received at the time of transaction, then its rate may change in the future which means that one of the traders will lose while the other one will gain more or less than what was negotiated at the time of executing the transaction. This is especially true when the currencies are measured by weight rather than numbers; metallic money may lose weight over time due to circulation or due to change of altitudes of the sale locations. The restrictions imposed by the Islamic law on the currency exchange transactions intend to protect both the seller and buyer of currencies and to avoid any conflicts which could arise from the sale of currencies. Furthermore, it leads to more stable currency exchange rates which forces the economists to focus on productive economy for achieving financial growth rather than on currency exchange rate fluctuations.
