Al-Ankabut - 29:7

وَالَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ لَنُكَفِّرَنَّ عَنْهُمْ سَيِّئَاتِهِمْ وَلَنَجْزِيَنَّهُمْ أَحْسَنَ الَّذِي كَانُوا يَعْمَلُونَ
[29:7]
And (as for) those who believe and do good, We will most certainly do away with their evil deeds and We will most certainly reward them the best of what they did.
Those who believe and work righteous deeds,- from them shall We blot out all evil (that may be) in them, and We shall reward them according to the best of their deeds.
And as for those who believe and do good works, We shall remit from them their evil deeds and shall repay them the best that they did.
