Al-Baqarah 2:275 الذين ياكلون الربا لا يقومون الا كما يقوم الذي يتخبطه الشيطان من المس ذالك بانهم قالوا انما البيع مثل الربا واحل الله البيع وحرم الربا فمن جاءه موعظة من ربه فانتهى فله ما سلف وامره الى الله ومن عاد فاولايك اصحاب النار هم فيها خالدون ٢٧٥

But those who take usury will rise up on the Day of Resurrection like someone tormented by Satan’s touch. That is because they say, ‘Trade and usury are the same,’ but God has allowed trade and forbidden usury. Whoever, on receiving God’s warning, stops taking usury may keep his past gains- God will be his judge- but whoever goes back to usury will be an inhabitant of the Fire, there to remain.
