those who consume interest cannot stand except as one stands who is being beaten by satan into insanity. that is because they say trade is like interest. but allah has permitted trade and has forbidden interest. so whoever has received an admonition from his lord and desists may have what is past and his affair rests with allah. but whoever returns to those are the companions of the fire they will abide eternally therein.
الذين يأكلون الربا لا يقومون إلا كما يقوم الذي يتخبطه الشيطان من المس ذلك بأنهم قالوا إنما البيع مثل الربا وأحل الله البيع وحرم الربا فمن جاءه موعظة من ربه فانتهى فله ما سلف وأمره إلى الله ومن عاد فأولئك أصحاب النار هم فيها خالدون
