3:130
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَأْكُلُوا۟ ٱلرِّبَوٰٓا۟ أَضْعَٰفًۭا مُّضَٰعَفَةًۭ ۖ وَٱتَّقُوا۟ ٱللَّهَ لَعَلَّكُمْ تُفْلِحُونَ
Yaaa ayyuhal lazeena aamanoo la taakuhur ribaaa ad'aafam mudaa'afatanw wattaqul laaha la'allakum tuflihoon
O ye who believe! Devour not usury, doubled and multiplied; but fear Allah; that ye may (really) prosper.
