Qur'an 3:135

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

And those who, when they do an evil thing or wrong themselves, remember Allah and implore forgiveness for their sins - Who forgiveth sins save Allah only? - and will not knowingly repeat (the wrong) they did.
