And it does not behoove a believer to kill a believer except by mistake, and whoever kills a believer by mistake, he should free a believing slave, and blood-money should be paid to his people unless they remit it as alms; but if he be from a tribe hostile to you and he is a believer, the freeing of a believing slave (suffices), and if he is from a tribe between whom and you there is a convenant, the blood-money should be paid to his people along with the freeing of a believing slave; but he who cannot find (a slave) should fast for two months successively: a penance from Allah, and Allah is Knowing, Wise. 92 And whoever kills a believer intentionally, his recompense is Hell to abide therein, and the Wrath and the Curse of Allah are upon him, and a great punishment is prepared for him. 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 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 Ranks from Him and forgiveness and mercy; and Allah is ever Forgiving, Merciful. 96
