It is not for a believer to take a believer's life except by mistake; and he who kills a believer by mistake should free a slave who is a believer, and pay blood-money to the victim's family unless they forego it as an act of charity. If he belonged to a community hostile to you but was himself a believer, then a slave who is a believer should be freed. In case he belonged to a people with whom you have a treaty, then give blood-money to his family and free a believing slave. But he who has no means (to do so) should fast for a period of two months continuously to have his sins forgiven by God, and God is all-knowing and all-wise. 92 And whoso slays a believer wilfully, his recompense is Gehenna, therein dwelling forever, and God will be wroth with him and will curse him, and prepare for him a mighty chastisement. 93 O you who have believed, when you go forth [to fight] in the cause of Allah, investigate; and do not say to one who gives you [a greeting of] peace "You are not a believer," aspiring for the goods of worldly life; for with Allah are many acquisitions. You [yourselves] were like that before; then Allah conferred His favor upon you, so investigate. Indeed Allah is ever, with what you do, Acquainted. 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 Ranks specially bestowed by Him, and Forgiveness and Mercy. For Allah is Oft-forgiving, Most Merciful. 96
