Legal Retribution
O believers, legal retribution is prescribed for you in cases of murder, the free for the free, the slave for the slave, and the female for the female. But if the victim’s family pardons the killer, then a fair settlement must be made. This is an alleviation and mercy from your Lord. Yet whoever transgresses after that will face a painful punishment.
2:178O ye who believe! Retaliation is prescribed for you in the matter of the murdered; the freeman for the freeman, and the slave for the slave, and the female for the female. And for him who is forgiven somewhat by his (injured) brother, prosecution according to usage and payment unto him in kindness. This is an alleviation and a mercy from your Lord. He who transgresseth after this will have a painful doom.
And in retribution, there is life for you, O people of understanding, so that you may become mindful.
2:179And there is life for you in retaliation, O men of understanding, that ye may ward off (evil).
The penalty for an evil act is its equivalent, but whoever forgives and seeks reconciliation will find their reward with Allah.
42:40The guerdon of an ill-deed is an ill the like thereof. But whosoever pardoneth and amendeth, his wage is the affair of Allah. Lo! He loveth not wrong-doers.
Those who defend themselves when wronged, there is no blame upon them.
42:41And whoso defendeth himself after he hath suffered wrong - for such, there is no way (of blame) against them.
Yet whoever is patient and forgives, this is true strength.
42:43And verily whoso is patient and forgiveth - lo! that, verily, is (of) the steadfast heart of things.
Then We took vengeance on those who sinned. It is Our duty to help the believers.
30:47Verily We sent before thee (Muhammad) messengers to their own folk. Then we took vengeance upon those who were guilty (in regard to them). To help believers is ever incumbent upon Us.
