Surah Ali 'Imran · Ayah 135

وَٱلَّذِينَ إِذَا فَعَلُوا۟ فَٰحِشَةً أَوْ ظَلَمُوٓا۟ أَنفُسَهُمْ ذَكَرُوا۟ ٱللَّهَ فَٱسْتَغْفَرُوا۟ لِذُنُوبِهِمْ وَمَن يَغْفِرُ ٱلذُّنُوبَ إِلَّا ٱللَّهُ وَلَمْ يُصِرُّوا۟ عَلَىٰ مَا فَعَلُوا۟ وَهُمْ يَعْلَمُونَ

Wallazeena izaa fa'aloo faahishatan aw zalamooo anfusahum zakarul laaha fastaghfaroo lizunoobihim; wa mai yaghfiruz zunooba illal laahu wa lam yusirroo 'alaa maa fa'aloo wa hum ya'lamooo

And those who, when they commit an immorality or wrong themselves [by transgression], remember Allah and seek forgiveness for their sins - and who can forgive sins except Allah? - and [who] do not persist in what they have done while they know.
