And whoever avenges himself after having been wronged - those have not upon them any cause [for blame].
The Saheeh International Quran Translation
وَلَمَنِ ٱنتَصَرَ بَعْدَ ظُلْمِهِۦ فَأُو۟لَٰٓئِكَ مَا عَلَيْهِم مِّن سَبِيلٍAnd whoever avenges himself after having been wronged - those have not upon them any cause [for blame].
