﴿ وَلَمَنِ ٱنتَصَرَ بَعْدَ ظُلْمِهِۦ فَأُو۟لَٰٓئِكَ مَا عَلَيْهِم مِّن سَبِيلٍ ﴾

“Yet indeed, as for any who defend themselves after having been wronged - no blame whatever attaches to them:”

And whoever defends himself after he has been wronged that is to say after the wrongdoer has wronged him — for such there will be no course of action against them no blame on them.
