It belongs not to a believer to slay a believer, except it be by error. If any slays a believer by error, then let him set free a believing slave, and bloodwit is to be paid to his family unless they forgo it as a freewill offering. If he belong to a people at enmity with you and is a believer, let the slayer set free a believing slave. If he belong to a people joined with you by a compact, then bloodwit is to be paid to his family and the slayer shall set free a believing slave. But if he finds not the means, let him fast two successive months -- God's turning; God is All-knowing, All-wise. 92 But whoever kills a believer intentionally - his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great punishment. 93 O People who Believe! When you go forth to fight in holy war, make a proper study, and do not say to the one who greets you, “You are not a Muslim,” – you seek the means of this worldly life; so with Allah are the bounties in plenty; you too were like this before, then Allah bestowed His favour on you, therefore you must make a proper study; indeed Allah knows whatever you do. 94 Those believers who stay behind, apart from those forced by necessity, are not equal to those who strive hard in God's cause with their possessions and their persons. God has given those who strive with their goods and their persons a higher rank than those who stayed behind. God has promised all a good reward; but far greater is the recompense of those who strive for Him -- 95 Ranks (of honour) from Him, and forgiveness, and mercy; and Allah is Oft Forgiving, Most Merciful. 96
