Mughirah said that concerning the saying of Allah, the Lord of Might: "And whoever kills a believer by mistake, let him free a believing slave and pay blood money to the heirs of the slain," Ibrahim said: When a Muslim is killed, this ruling is for him and for his Muslim heirs. And concerning the verse: "And if the slain is from a people who are your enemy and he is a believer," he said: It is the Muslim man who is killed while his people are polytheists who have no covenant between them and the Messenger of Allah (peace and blessings be upon him); then it is binding upon the killer to free a Muslim slave. And if someone killed a Muslim who belonged to a people of polytheists who had a covenant with the Messenger of Allah (peace and blessings be upon him), then he is required to free a Muslim slave, and his blood money will be paid to the people who had a covenant with the Messenger of Allah (peace and blessings be upon him). His inheritance will be for the Muslims, and his blood money will be for that polytheist people who had a covenant with the Messenger of Allah (peace and blessings be upon him). So the Muslims will inherit his estate, and his blood money will be for his people, because they are the ones who pay blood money on his behalf.
