On the other hand are those who eat usury. In greed of money, they run around like someone who has been bitten by a snake. They claim that trade is like usury. This is not so. Trade is the return on labor that is permissible (53:39), while usury is the return on money. That is why Allah, in His Infinite Wisdom, has permitted trade and forbidden usury. One to whom the clear Admonition has come from his Sustainer, must abstain from taking usury forthwith. What he has taken in the past, he may keep and his judgment rests with Allah. (It is better for him to return the interest he has earned if possible, but the law shall not force him to do so). As for him who returns to usury, such are the rightful companions of the Fire to abide therein. (Satan=Serpent).
