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

As for those who devour interest,¹ they behave as the one whom Satan has confounded with his touch.² Seized in this state they say: “Buying and selling is but a kind of interest,”³ even though Allah has made buying and selling lawful, and interest unlawful.⁴ Hence, he who receives this admonition from his Lord, and then gives up (dealing in interest), may keep his previous gains, and it will be for Allah to judge him.⁵ As for those who revert to it, they are the people of the Fire, and in it shall they abide.
