It is not rightful for a Muslim to kill another Muslim, unless it occurs by mistake; and the one who mistakenly kills a Muslim must set free a Muslim slave and pay blood-money to the family of the slain, except if they forego it; and if the victim is of a people who are hostile to you, and the killer is a Muslim, then only the setting free of a Muslim slave (is obligatory); and if the victim is from a people between whom and you there is a treaty, then blood-money must be paid to his family and the setting free of a Muslim slave; therefore one who has no means must fast for two consecutive months; this is his penance before Allah; and Allah is All Knowing, Wise. 92 Whoso slayeth a believer of set purpose, his reward is hell for ever. Allah is wroth against him and He hath cursed him and prepared for him an awful doom. 93 O believers, when you are journeying in the path of God, be discriminating, and do not say to him who offers you a greeting, 'Thou art not a believer,' seeking the chance goods of the present life. With God are spoils abundant. So you were aforetime; but God has been gracious to you. So be discriminating; surely God is aware of the things you do. 94 Such believers as sit at home -- unless they have an injury -- are not the equals of those who struggle in the path of God with their possessions and their selves. God has preferred in rank those who struggle with their possessions and their selves over the ones who sit at home; yet to each God has promised the reward most fair; and God has preferred those who struggle over the ones who sit at home for the bounty of a mighty wage, 95 Degrees of rank from Him, and forgiveness and mercy. Allah is ever Forgiving, Merciful. 96
