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 [Hence,] O you who have attained to faith, when you go forth [to war] in God's cause, use your discernment, and do not - out of a desire for the fleeting gains of this worldly life - say unto anyone who offers you the greeting of peace, "Thou art not a believer" for with God there are gains abundant. You, too, were once in the same condition - but God has been gracious unto you. Use, therefore, your discernment: verily, God is always aware of what 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 high ranks conferred by Him as well as forgiveness and mercy. God is forgiving and merciful. 96
