Al-An'am 6:160
مَن جَآءَ بِٱلْحَسَنَةِ فَلَهُۥ عَشْرُ أَمْثَالِهَا ۖ وَمَن جَآءَ بِٱلسَّيِّئَةِ فَلَا يُجْزَىٰٓ إِلَّا مِثْلَهَا وَهُمْ لَا يُظْلَمُونَ
Man jaa bilhasanatifalahu AAashru amthaliha waman jaa bissayyi-atifala yujza illa mithlaha wahum layuthlamoon
Whoever comes [on the Day of Judgement] with a good deed will have ten times the like thereof [to his credit], and whoever comes with an evil deed will not be recompensed except the like thereof; and they will not be wronged.
Whoever comes with a good deed will receive ten times as much, and whoever comes with an evil deed will be requited with no more than the like of it, and they shall not be wronged.
