But as for one who had repented, believed, and done righteousness, it is promised by Allah that he will be among the successful — Surah Al-Qasas 67

Say, 'O My servants who have transgressed against themselves, do not despair of the mercy of Allah. Indeed, Allah forgives all sins.'

Whoever wrongs himself and seeks Allah's forgiveness will find Allah Forgiving.

There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers.
