This one plus the next eight verses, consist of a series of economical, social, and educational brief outlines. First of all the believers are addressed and said to them: ``Devour not usury with compound interests, and know that prosperity is not in greed, but rather in giving.''

      USURY was deeply rooted in trades and social affairs of the Pagan Arabs, and the Holy Qurän proceeded to cut it down gradually and in four steps or stages:

      1- In the verse; S 30: 39 it has sufficed with a piece of ethical advice that: ``Whatever you get out of usury in order to increase the property of people, it shall not increase with Allah. But whatever you give in charity, desiring Allah's pleasure, you shall have it manifold.''

      2- In the verse; S 4:161 USURY is declared as one of the ugly and offensive customs of the Jews: ``And their taking usury though they were forbidden it. And their devouring the properties of people falsely ...''

      3- In the verse; S 2: 275-9, all sorts of usury has been forbidden and declared unlawful and is equal to fight against God: ``Those who devour usury cannot arise except as one whom Satan by his touch has driven to madness. That is because they say; trade is like usury....''

      O, you who believe! Fear Allah and give up what remains of your demands for usury ... And if you do it not, then take notice of war from Allah and His apostle.''

      4- And at last, through this verse (S 3: 130) the unlawfulness of USURY is clearly announced, and one sort of usury which is the worst of all has been referred to, and that is the progressive interest of usury - doubled and redoubled in which the interest is regularly added to the principal, and it is called the COMPOUND INTEREST.
