It is not for a believer to kill a believer unless (it be) by mistake. He who hath killed a believer by mistake must set free a believing slave, and pay the blood-money to the family of the slain, unless they remit it as a charity. If he (the victim) be of a people hostile unto you, and he is a believer, then (the penance is) to set free a believing slave. And if he cometh of a folk between whom and you there is a covenant, then the blood-money must be paid unto his folk and (also) a believing slave must be set free. And whoso hath not the wherewithal must fast two consecutive months. A penance from Allah. Allah is Knower, 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 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 The Muslims who stay back from holy war without proper excuse, are not equal to the Muslims who fight in Allah's cause with their wealth and lives; Allah has bestowed higher ranks to the warriors who strive with their wealth and lives, than those who stay back; and Allah has promised good to all; and Allah has favoured the warriors upon those who stay back, with a great reward. 95 Degrees of rank from Him, and forgiveness and mercy. Allah is ever Forgiving, Merciful. 96
