No believer should kill another believer, unless it be by mistake. Anyone who kills a believer by mistake should free a believing slave and pay blood money to the victim's relatives unless they forego it as an act of charity. If the victim belongs to a people at war with you, but is a believer, then the compensation is to free a believing slave. If he belongs to a people with whom you have a treaty, then blood-money should be handed over to his relatives and a believing slave set free. Anyone who lacks the means must fast for two consecutive months. Such is the penance imposed by God. God is all knowing and wise.
