Surah An-Nisa, Verse 110

وَمَن يَعۡمَلۡ سُوٓءًا أَوۡ يَظۡلِمۡ نَفۡسَهُۥ ثُمَّ يَسۡتَغۡفِرِ ٱللَّهَ يَجِدِ ٱللَّهَ غَفُورٗا رَّحِيمٗا١١٠

waman yaʿmal sūan aw yaẓlim nafsahu thumma yastaghfiri l-laha yajidi l-laha ghafūran raḥīman

And whoever does a wrong or wrongs himself but then seeks forgiveness of Allāh will find Allāh Forgiving and Merciful.
