Ibn Majah transmitted it on the authority of Ibn ‘Abbas.

Abu Shuraih al-Khuza'i told that he heard God's Messenger say,“If a relative of anyone is killed, or if he suffers khabal, which means a wound, he may choose one of three things, but if he wants anything more* you must restrain him. He may retaliate, or forgive, or receive compensation; but if he accepts one of these and afterwards asks something more, he will go to hell for ever and ever.”Darimi transmitted it. * Literally“the fourth.”

Ta’us, on the authority of Ibn ‘Abbas, reported God’s Messenger as saying,“If anyone is killed in error when people are throwing stones, or by beating with whips, or striking with a stick, it is accidental and the compensation for accidental death is due.* But if anyone kills someone deliberately retaliation is due, and if anyone tries to prevent it God’s curse and anger will rest on him, and neither supererogatory nor obligatory acts will be accepted from him.”Abu Dawud and Nasa’i transmitted it. *These are instances in which the actual person who killed him is not clearly known, or where there was no intention to kill.

Jabir reported God’s Messenger as saying,“I will not forgive any-one who kills after accepting blood wit.”Abu Dawud transmitted it.

Abud Darda’ told that he heard God’s Messenger say,“No one will suffer any bodily injury and forgive it* without God raising him a degree for it and removing a sin from him.”Tirmidhi and Ibn Majah transmitted it. * Literally "give it as sadaqa.”

Sa'id b. al-Musayyib told that ‘Umar b. al-Khattab killed five or seven people for one man whom they had killed treacherously, ‘Umar saying.“If the people of San'a’ had conspired against him I would have killed them all.”Malik transmitted it.

Bukhari transmitted something similar on the authority of Ibn ‘Umar.

Jundub said he was told by so and so that God’s Messenger said,“On the day of resurrection the man who has been killed will bring the one who killed him and say, ‘Ask this man why he killed me,’ and he will say, ‘I killed him on account of so and so's property’.”* Jundub said,“Avoid that.”Nasa’i transmitted it. * There is some doubt as to whether the word is to be read milk or mulk. The translation above follows the former the latter is the correct reading it would require "in the time of so and so's reign." This, however, does not seem to suit the context.

Abu Huraira reported God’s Messenger as saying,“If anyone helps in killing a believer to the extent of half a word,* he will meet God with ‘Despairing of God’s mercy’ written on his forehead.”Ibn Majah transmitted it. * This is taken to mean that it is a serious matter even to utter half the word which expresses an intention to kill a believer.

Ibn ‘Umar reported the Prophet as saying,“If a man seizes a man and another kills him, the one who killed him is to be killed and the one who seized him is to be imprisoned.”Daraqutni transmitted it.
