The recompense for an injury is an injury equal thereto (in degree): but if a person forgives and makes reconciliation, his reward is due from Allah: from (Allah) loveth not those who do wrong. But indeed if any do help and defend themselves after a wrong (done) to them, against such there is no cause of blame. The blame is only against those who oppress men and wrong-doing and insolently transgress beyond bounds through the land, defying right and justice: for such there will be a penalty grievous. But indeed if any show patience and forgive, that would truly be an exercise of courageous will and resolution in the conduct of affairs.
– Holy Qur’an
