29:7 · Al-Ankaboot
وَالَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ لَنُكَفِّرَنَّ عَنْهُمْ سَيِّئَاتِهِمْ وَلَنَجْزِيَنَّهُمْ أَحْسَنَ الَّذِي كَانُوا يَعْمَلُونَ
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.
