Al-An'aam (6:160)
مَن جَاۤءَ بِٱلۡحَسَنَةِ فَلَهُۥ عَشۡرُ أَمۡثَالِهَاۖ وَمَن جَاۤءَ بِٱلسَّیِّئَةِ فَلَا یُجۡزَىٰۤ إِلَّا مِثۡلَهَا وَهُمۡ لَا یُظۡلَمُونَ
Whoso bringeth a good deed will receive tenfold the like thereof, while whoso bringeth an ill-deed will be awarded but the like thereof; and they will not be wronged.
— Mohammed Marmaduke William Pickthall
