It is not for a believer to slay another believer unless by mistake. And he who has slain a believer by mistake, his atonement is to set free from bondage a believing person and to pay blood-money to his heirs, unless they forgo it by way of charity. And if the slain belonged to a hostile people, but was a believer, then the atonement is to set free from bondage a believing person. And if the slain belonged to a (non-Muslim) people with whom you have a covenant, then the atonement is to pay the blood-money to his heirs, and to set free from bondage a believing person. But he who cannot (free a slave) should fast for two consecutive months. This is the penance ordained by Allah. Allah is All-Knowing, All-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 believers, when you go out on a journey in the way of God, be discreet and do not say to anyone who greets you in peace: "You are not a believer." You desire the gain of earthly life, but there are prizes in plenty with God. You were also like him (an unbeliever) in the past, but God has been gracious to you. So be careful and discreet, for God is aware of what 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 Ranks specially bestowed by Him, and Forgiveness and Mercy. For Allah is Oft-forgiving, Most Merciful. 96
