Al-Qasas 28:16

قَالَ رَبِّ إِنِّى ظَلَمْتُ نَفْسِى فَٱغْفِرْ لِى فَغَفَرَ لَهُۥٓ ۚ إِنَّهُۥ هُوَ ٱلْغَفُورُ ٱلرَّحِيمُ

Qāla rabbi innī ẓalamtu nafsī fa-igh'fir lī faghafara lahu innahu huwa l-ghafūru l-raḥīmu

He said, "My Lord, indeed I have wronged myself, so forgive me," and He forgave him. Indeed, He is the Forgiving, the Merciful.
