The basic principle of Islamic banking is the prohibition of Riba- (Usury - or interest):
"While a basic tenant of Islamic banking - the outlawing of riba, a term that encompasses not only the concept of usury, but also that of interest - has seldom been recognised as applicable beyond the Islamic world, many of its guiding principles have. The majority of these principles are based on simple morality and common sense, which form the bases of many religions, including Islam.
"The universal nature of these principles is immediately apparent even at a cursory glance of non-Muslim literature. Usury was prohibited in both the Old and New Testaments of the Bible, while Shakespeare and many other writers, particularly those writing in the 19th century, have attacked the barbarity of the practice. Much of the morality championed by Victorian writers such as Dickens - ranging from the equitable distribution of wealth through to man's fundamental right to work - is clearly present in modern Islamic society.
"Although the western media frequently suggest that Islamic banking in its present form is a recent phenomenon, in fact, the basic practices and principles date back to the early part of the seventh century." (Islamic Finance: A Euromoney Publication, 1997)
It is evident that Islamic finance was practiced predominantly in the Muslim world throughout the Middle Ages, fostering trade and business activities. In Spain and the Mediterranean and Baltic States, Islamic merchants became indispensable middlemen for trading activities. It is claimed that many concepts, techniques, and instruments of Islamic finance were later adopted by European financiers and businessmen.
The revival of Islamic banking coincided with the world-wide celebration of the advent of the 15th Century of Islamic calendar (Hijra) in 1976. At the same time financial resources of Muslims particularly those of the oil producing countries, received a boost due to rationalization of the oil prices, which had hitherto been under the control of foreign oil Corporations. These events led Muslims' to strive to model their lives in accordance with the ethics and philosophy of Islam.
Disenchantment with the value neutral capitalist and socialist financial systems led not only Muslims but also others to look for ethical values in their financial dealings and in the West some financial organisations have opted for ethical operations.
Islam not only prohibits dealing in interest but also in liquor, pork, gambling, pornography and anything else, which the Shariah (Islamic Law) deems Haram (unlawful). Islamic banking is an instrument for the development of an Islamic economic order. Some of the salient features of this order may be summed up as:
The Islamic financial system employs the concept of participation in the enterprise, utilizing the funds at risk on a profit-and- loss-sharing basis. This by no means implies that investments with financial institutions are necessarily speculative. This can be excluded by careful investment policy, diversification of risk and prudent management by Islamic financial institutions.
It is possible, that investment in Islamic financial institutions can provide potential profit in proportion to the risk assumed to satisfy the differing demands of participants in the contemporary environment and within the guidelines of the Shariah.
The concept of profit-and-loss sharing, as a basis of financial transactions is a progressive one as it distinguishes good performance from the bad and the mediocre. This concept therefore encourages better resource management.
Islamic banks are structured to retain a clearly differentiated status between shareholders' capital and clients' deposits in order to ensure correct profit-sharing according to Islamic Law.
