Surah An-Nisa, ayah 110

وَمَن يَعۡمَلۡ سُوٓءًا أَوۡ يَظۡلِمۡ نَفۡسَهُۥ ثُمَّ يَسۡتَغۡفِرِ ٱللَّهَ يَجِدِ ٱللَّهَ غَفُورٗا رَّحِيمٗا ١١٠

Waman ya'mal sū'an aw yazlim nafsahū thumma yastaghfirillāha yajidillāha ghafūrar rahīmā

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