Quran 3:135 Ali 'Imran, ayah 135 of 200

وَٱلَّذِينَ إِذَا فَعَلُوا۟ فَـٰحِشَةً أَوْ ظَلَمُوٓا۟ أَنفُسَهُمْ ذَكَرُوا۟ ٱللَّهَ فَٱسْتَغْفَرُوا۟ لِذُنُوبِهِمْ وَمَن يَغْفِرُ ٱلذُّنُوبَ إِلَّا ٱللَّهُ وَلَمْ يُصِرُّوا۟ عَلَىٰ مَا فَعَلُوا۟ وَهُمْ يَعْلَمُونَ ۝١٣٥

3:135 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.
