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 If anyone kills a believer deliberately, his reward shall be eternal Hell. God will condemn him and reject him, and prepare for him a terrible punishment. 93 Believers, when you go forth in the cause of God, make due investigation and do not say to those who offer you the greeting of peace, "You are no believer!" because you seek the good things of this life. With God there are good things in plenty. You yourself were in the same position before, but God conferred His special favour on you. Therefore, take care to investigate. Surely God is well-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 For them are higher ranks with God, and forgiveness and grace; and God is forgiving and kind. 96
