Those who consume interest1 cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, "Trade is [just] like interest." But Allāh 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 Allāh. But whoever returns [to dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.
