a.w.). The Shari'ah disallows Riba and there is now a general consensus among Muslim economists that Riba is not restricted to usury but encompasses interest as well. The Qur'an is clear about the prohibition of Riba, which is sometimes defined as excessive interest. "O You who believe! Fear Allah and give up that remains of your demand for usury, if you are indeed believers." Muslim scholars have accepted the word Riba to mean any fixed or guaranteed interest payment on cash advances or on deposits. Several Qur'anic passages expressly admonish the faithful to shun interest. .
The rules regarding Islamic finance are quite simple and can be summed up as follows: .
a) Any predetermined payment over and above the actual amount of principal is prohibited. .
Islam allows only one kind of loan and that is qard-el-hassan (literally good loan) whereby the lender does not charge any interest or additional amount over the money lent. Traditional Muslim jurists have construed this principle so strictly that, according to one commentator "this prohibition applies to any advantage or benefits that the lender might secure out of the qard (loan) such as riding the borrower's mule, eating at his table, or even taking advantage of the shade of his wall." The principle derived from the quotation emphasises that associated or indirect benefits are prohibited. .
b) the lender must share in the profits or losses arising out of the enterprise for which the money was lent. .
Islam encourages Muslims to invest their money and to become partners in order to share profits and risks in the business instead of becoming creditors. As defined in the Shari'ah, or Islamic law, Islamic finance is based on the belief that the provider of capital and the user of capital should equally share the risk of business ventures, whether those are industries, farms, service companies or simple trade deals. Translated into banking terms, the depositor, the bank and the borrower should all share the risks and the rewards of financing business ventures.
