Ash-Shura - 42:41

وَلَمَنِ انتَصَرَ بَعْدَ ظُلْمِهِ فَأُوْلَئِكَ مَا عَلَيْهِم مِّن سَبِيلٍ
[42:41]
And whoever defends himself after his being oppressed, these it is against whom there is no way (to blame).
But indeed if any do help and defend themselves after a wrong (done) to them, against such there is no cause of blame.
And whoso defendeth himself after he hath suffered wrong - for such, there is no way (of blame) against them.
