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 Whoso slayeth a believer of set purpose, his reward is hell for ever. Allah is wroth against him and He hath cursed him and prepared for him an awful doom. 93 O People who Believe! When you go forth to fight in holy war, make a proper study, and do not say to the one who greets you, “You are not a Muslim,” – you seek the means of this worldly life; so with Allah are the bounties in plenty; you too were like this before, then Allah bestowed His favour on you, therefore you must make a proper study; indeed Allah knows whatever you do. 94 Among the believers, those who stay at home without a good reason are not equal to those who strive for the cause of God in person or with their property. To those who strive for His cause in person or with their property, God has granted a higher rank than to those who stay at home. God has promised that everyone will receive his proper share of the reward but He will grant a much greater reward to those striving for His cause than to those who stay home (for no reason). 95 God will grant those who strive high ranks, forgiveness, and mercy. He is All-forgiving and All-merciful. 96
