Or He could destroy them for what they earned; but He pardons much — Surah Ash-Shura 34

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.
