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

Those who eat Ribâ ¹ (usury) will not stand (on the Day of Resurrection) except like the standing of a person beaten by Shaitân (Satan) leading him to insanity. That is because they say: "Trading is only like Ribâ (usury)," whereas Allâh has permitted trading and forbidden Ribâ (usury). So whosoever receives an admonition from his Lord and stops eating Ribâ (usury) shall not be punished for the past; his case is for Allâh (to judge); but whoever returns [to Ribâ (usury)], such are the dwellers of the Fire - they will abide therein.
