2:275
ٱلَّذِينَ يَأْكُلُ ونَ ٱل رِّبَوٰا۟ لَا يَقُومُ ونَ إِلَّا كَ مَا يَقُومُ ٱلَّذِى يَتَخَبَّطُ هُ ٱل شَّيْطَٰنُ مِنَ ٱلْ مَسِّ ذَٰلِكَ بِ أَنَّ هُمْ قَالُ وٓا۟ إِنَّ مَا ٱلْ بَيْعُ مِثْلُ ٱل رِّبَوٰا۟ وَ أَحَلَّ ٱللَّهُ ٱلْ بَيْعَ وَ حَرَّمَ ٱل رِّبَوٰا۟ فَ مَن جَآءَ هُۥ مَوْعِظَةٌ مِّن رَّبِّ هِۦ فَ ٱنتَهَىٰ فَ لَ هُۥ مَا سَلَفَ وَ أَمْرُ هُۥٓ إِلَى ٱللَّهِ وَ مَنْ عَادَ فَ أُو۟لَٰٓئِكَ أَصْحَٰبُ ٱل نَّارِ هُمْ فِي هَا خَٰلِدُونَ
Those who consume interest 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 Allah 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 Allah. But whoever returns to [dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.
