Surah Al-'Ankabut, ayah 7

29:7

وَٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّٰلِحَٰتِ لَنُكَفِّرَنَّ عَنۡهُمۡ سَيِّـَٔاتِهِمۡ وَلَنَجۡزِيَنَّهُمۡ أَحۡسَنَ ٱلَّذِي كَانُواْ يَعۡمَلُونَ ٧

Walladhīna āmanū wa'amilus-sālihāti lanukaffiranna 'anhum sayyi'ātihim walanajziyannahum ahsanal-ladhī kānū ya'malūn

And those who believe and do righteous deeds - We will surely remove from them their misdeeds and will surely reward them according to the best of what they used to do.
