6:160
مَنْ جَٓاءَ بِالْحَسَنَةِ فَلَهُ عَشْرُ اَمْثَالِهَاۚ وَمَنْ جَٓاءَ بِالسَّیِّئَةِ فَلَا یُجْزٰٓى اِلَّا مِثْلَهَا وَهُمْ لَا یُظْلَمُونَ
Man jaa bialhasanati falahu AAashru amthaliha waman jaa bialssayyiati fala yujza illa mithlaha wahum la yuthlamoona
Translations

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
