Al An’am Ayah 160

مَن جَآءَ بِٱلْحَسَنَةِ فَلَهُۥ عَشْرُ أَمْثَالِهَا‌ۖ وَمَن جَآءَ بِٱلسَّيِّئَةِ فَلَا يُجْزَىٰٓ إِلَّا مِثْلَهَا وَهُمْ لَا يُظْلَمُونَ ١٦٠ Whoever comes with a good deed will be rewarded tenfold. But whoever comes with a bad deed will be punished for only one. None will be wronged.
