Surah Ash-Shuraوَٱلَّذِينَ يَجۡتَنِبُونَ كَبَـٰٓئِرَ ٱلۡإِثۡمِ وَٱلۡفَوَٰحِشَ وَإِذَا مَا غَضِبُواْ هُمۡ يَغۡفِرُونَ
Those who avoid the major sins and indecent, shameful deeds (which are indeed to be counted among major sins), and when they become angry, even then they forgive (rather than retaliate in kind)
