Al-Qasas - 28:84

مَن جَاء بِالْحَسَنَةِ فَلَهُ خَيْرٌ مِّنْهَا وَمَن جَاء بِالسَّيِّئَةِ فَلَا يُجْزَى الَّذِينَ عَمِلُوا السَّيِّئَاتِ إِلَّا مَا كَانُوا يَعْمَلُونَ
[28:84]
Whoever brings good, he shall have better than it, and whoever brings evil, those who do evil shall not be rewarded (for) aught except what they did.
If any does good, the reward to him is better than his deed; but if any does evil, the doers of evil are only punished (to the extent) of their deeds.
Whoso bringeth a good deed, he will have better than the same; while as for him who bringeth an ill-deed, those who do ill-deeds will be requited only what they did.
