Surah Al-Qasas, Verse 16

قَالَ رَبِّ إِنِّي ظَلَمۡتُ نَفۡسِي فَٱغۡفِرۡ لِي فَغَفَرَ لَهُۥٓۚ إِنَّهُۥ هُوَ ٱلۡغَفُورُ ٱلرَّحِيمُ١٦

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.
