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 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 believers, when you are journeying in the path of God, be discriminating, and do not say to him who offers you a greeting, 'Thou art not a believer,' seeking the chance goods of the present life. With God are spoils abundant. So you were aforetime; but God has been gracious to you. So be discriminating; surely God is aware of the things you do. 94 The faithful who sit idle, other than those who are disabled, are not equal to those who fight in the way of God with their wealth and lives. God has exalted those in rank who fight for the faith with their wealth and souls over those who sit idle. Though God's promise of good is for all, He has granted His favour of the highest reward to those who struggle in preference to those who sit at home. 95 For them are ranks, forgiveness, and favours from Him. Allah is All-Forgiving, All-Compassionate. 96
