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 And whoever kills a believer intentionally, his punishment is hell; he shall abide in it, and Allah will send His wrath on him and curse him and prepare for him a painful chastisement. 93 O you who believe! when you go to war in Allah's way, make investigation, and do not say to any one who offers you peace: You are not a believer. Do you seek goods of this world's life! But with Allah there are abundant gains; you too were such before, then Allah conferred a benefit on you; therefore make investigation; surely Allah is aware of what you 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 Ranks specially bestowed by Him, and Forgiveness and Mercy. For Allah is Oft-forgiving, Most Merciful. 96
