إِلَّا مَن تَابَ وَءَامَنَ وَعَمِلَ عَمَلًا صَـٰلِحًا فَأُو۟لَـٰٓئِكَ يُبَدِّلُ ٱللَّهُ سَيِّـَٔاتِهِمْ حَسَنَـٰتٍ ۗ وَكَانَ ٱللَّهُ غَفُورًا رَّحِيمًا

"Except for those who repent, believe and do righteous work. For them Allāh will replace their evil deeds with good. And ever is Allāh Forgiving and Merciful."

A short reflection
For those who repent and do righteous deeds, Allah will replace their bad deeds with good ones.
