Sale (Al-Bay') in the Holy Quran

﴿ٱلَّذِينَ يَأۡكُلُونَ ٱلرِّبَوٰاْ لَا يَقُومُونَ إِلَّا كَمَا يَقُومُ ٱلَّذِي يَتَخَبَّطُهُ ٱلشَّيۡطَٰنُ مِنَ ٱلۡمَسِّۚ ذَٰلِكَ بِأَنَّهُمۡ قَالُوٓاْ إِنَّمَا ٱلۡبَيۡعُ مِثۡلُ ٱلرِّبَوٰاْۗ وَأَحَلَّ ٱللَّهُ ٱلۡبَيۡعَ وَحَرَّمَ ٱلرِّبَوٰاْۚ فَمَن جَآءَهُۥ مَوۡعِظَةٞ مِّن رَّبِّهِۦ فَٱنتَهَىٰ فَلَهُۥ مَا سَلَفَ وَأَمۡرُهُۥٓ إِلَى ٱللَّهِۖ وَمَنۡ عَادَ فَأُوْلَٰٓئِكَ أَصۡحَٰبُ ٱلنَّارِۖ هُمۡ فِيهَا خَٰلِدُونَ ﴾ [Al-Baqarah: 275]

But whoever returns to [dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.
