Quran

وَٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّـٰلِحَٰتِ لَنُكَفِّرَنَّ عَنۡهُمۡ سَيِّـَٔاتِهِمۡ وَلَنَجۡزِيَنَّهُمۡ أَحۡسَنَ ٱلَّذِي كَانُواْ يَعۡمَلُونَ

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
