And it does not behoove a believer to kill a believer except by mistake, and whoever kills a believer by mistake, he should free a believing slave, and blood-money should be paid to his people unless they remit it as alms; but if he be from a tribe hostile to you and he is a believer, the freeing of a believing slave (suffices), and if he is from a tribe between whom and you there is a convenant, the blood-money should be paid to his people along with the freeing of a believing slave; but he who cannot find (a slave) should fast for two months successively: a penance from Allah, and Allah is Knowing, Wise. 92 And he who slays a believer wilfully his reward is Hell, where he will abide. Allah's wrath is against him and He has cast His curse upon him, and has prepared for him a great chastisement. 93 O Ye who believe! when ye march forth in the way of Allah, make things clear and say not unto one who giveth you a salutation: thou art none of a believer, seeking the perishable goods of the life of the world; for with Allah are spoils abundant. Even thus were ye aforetime, then Allah favoured you. So make things clear; verily Allah is of that which ye work ever Aware. 94 Those of the believers who sit still, other than those who have a (disabling) hurt, are not on an equality with those who strive in the way of Allah with their wealth and lives. Allah hath conferred on those who strive with their wealth and lives a rank above the sedentary. Unto each Allah hath promised good, but He hath bestowed on those who strive a great reward above the sedentary; 95 Ranks (of honour) from Him, and forgiveness, and mercy; and Allah is Oft Forgiving, Most Merciful. 96
