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. 92 And whosoever slayeth a believer intentionally, His meed is Hell, as an abider therein; and Allah shall be wroth with him and shall curse him, and shall get ready for him a torment terrible. 93 O you who have believed, when you go forth [to fight] in the cause of Allah, investigate; and do not say to one who gives you [a greeting of] peace "You are not a believer," aspiring for the goods of worldly life; for with Allah are many acquisitions. You [yourselves] were like that before; then Allah conferred His favor upon you, so investigate. Indeed Allah is ever, with what you do, Acquainted. 94 The holders back from among the believers, not having any injury, and those who strive hard in Allah's way with their property and their persons are not equal; Allah has made the strivers with their property and their persons to excel the holders back a (high) degree, and to each (class) Allah has promised good; and Allah shall grant to the strivers above the holders back a mighty reward: 95 For them are ranks, forgiveness, and favours from Him. Allah is All-Forgiving, All-Compassionate. 96
