(178) O you who have believed, prescribed for you is legal retribution for those murdered - the free for the free, the slave for the slave, and the female for the female. But whoever overlooks from his brother anything, then there should be a suitable follow-up and payment to him with good conduct. This is an alleviation from your Lord and a mercy. But whoever transgresses after that will have a painful punishment.
(126) And if you punish [an enemy, O believers], punish with an equivalent of that with which you were harmed. But if you are patient - it is better for those who are patient.
(60) That [is so]. And whoever responds [to injustice] with the equivalent of that with which he was harmed and then is tyrannized - Allah will surely aid him. Indeed, Allah is Pardoning and Forgiving.
(39) And those who, when tyranny strikes them, they defend themselves. (40) And the retribution for an evil act is an evil one like it, but whoever pardons and makes reconciliation - his reward is [due] from Allah. Indeed, He does not like wrongdoers. (41) And whoever avenges himself after having been wronged - those have not upon them any cause [for blame].
A slave girl went out wearing jewelry, so a Jew caught her, crushed her head and took what was on her. She was brought to the Messenger of Allah, and she was still breathing. The Messenger of Allah said to her: Who killed you? So-and-so? She shook her head, no. He said: So-and-so? She shook her head, no. He said: So-and-so the Jew? She nodded her head, yes. The Messenger of Allah (PBUH) seized him and crushed his head between two stones.
