And never is it for a believer to kill a believer except by mistake. And whoever kills a believer by mistake - then the freeing of a believing slave and a compensation payment presented to the deceased's family [is required] unless they give [up their right as] charity. But if the deceased was from a people at war with you and he was a believer - then [only] the freeing of a believing slave; and if he was from a people with whom you have a treaty - then a compensation payment presented to his family and the freeing of a believing slave. And whoever does not find [one or cannot afford to buy one] - then [instead], a fast for two months consecutively, [seeking] acceptance of repentance from Allah. And Allah is ever Knowing and Wise. 92 But whoever deliberately slays another believer, his requital shall be hell, therein to abide; and God will condemn him, and will reject him, and will prepare for him awesome suffering. 93 O ye who believe! When ye go forth (to fight) in the way of Allah, be careful to discriminate, and say not unto one who offereth you peace: "Thou art not a believer," seeking the chance profits of this life (so that ye may despoil him). With Allah are plenteous spoils. Even thus (as he now is) were ye before; but Allah hath since then been gracious unto you. Therefore take care to discriminate. Allah is ever Informed of what ye 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 in ranks standing before Him, forgiveness and mercy; surely God is All-forgiving, All-compassionate. 96
