It is unlawful for a believer to kill another believer, accidents excepted. He that accidentally kills a believer must free one Muslim slave and pay blood-money to the family of the victim, unless they choose to give it away in alms. If the victim be a Muslim from a hostile tribe, the penalty is the freeing of one Muslim slave. But if the victim be a member of an allied tribe, then blood-money must be paid to his family and a Muslim slave set free. He that lacks the means must fast two consecutive months. Such is the penance imposed by God: God is all-knowing and wise.
