those who swallow down usury cannot arise except as one whom shaitan has prostrated by touch does rise. that is because they say trading is only like usury and allah has allowed trading and forbidden usury. to whomsoever then the admonition has come from his lord then he desists he shall have what has already passed and his affair is in the hands of allah and whoever returns these are the inmates of the fire they shall abide in it.
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
