A believer killeth not a believer but by mischance: and whoso killeth a believer by mischance shall be bound to free a believer from slavery; and the blood-money shall be paid to the family of the slain, unless they convert it into alms. But if the slain believer be of a hostile people, then let him confer freedom on a slave who is a believer; and if he be of a people between whom and yourselves there is an alliance, then let the blood-money be paid to his family, and let him set free a slave who is a believer: and let him who hath not the means, fast two consecutive months. This is the penance enjoined by God; and God is Knowing, Wise!
