Quran 42:40 — Consultation (Al-Shoora)

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.

[42:39] When gross injustice befalls them, they stand up for their rights.

[42:41] Certainly, those who stand up for their rights, when injustice befalls them, are not committing any error.
