It is not for a believer to kill another believer, except that it is by error. Whosoever kills a believer in error, let him free a believing slave, and ransom is to be handed to his family, unless they forgo being charitable. If he belonged to a people who are your enemies and is a believer then, the setting free of a believing slave. If he belonged to a people in which there is between you and them a treaty, then a ransom is to be handed to his family and the setting free of a believing slave. But, if he does not find (the means) let him fast two consecutive months in repentance to Allah. And Allah is the Knower, the Wise. 92 The punishment for one who purposely slays a believer will be to live in hell fire forever. God is angry with him and has condemned him. He has prepared for him a great torment. 93 Believers, when you go forth in the cause of God, make due investigation and do not say to those who offer you the greeting of peace, "You are no believer!" because you seek the good things of this life. With God there are good things in plenty. You yourself were in the same position before, but God conferred His special favour on you. Therefore, take care to investigate. Surely God is well-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 (of honour) from Him, and forgiveness, and mercy; and Allah is Oft Forgiving, Most Merciful. 96
