Quran 42:41 — Consultation (Al-Shoora)

Certainly, those who stand up for their rights, when injustice befalls them, are not committing any error.

[42:40] Although the just requital for an injustice is an equivalent retribution, those who pardon and maintain righteousness are rewarded by GOD. He does not love the unjust.

[42:42] The wrong ones are those who treat the people unjustly, and resort to aggression without provocation. These have incurred a painful retribution.
