It is not for a believer to kill a believer except (that it be) by mistake, and whosoever kills a believer by mistake, (it is ordained that) he must set free a believing slave and a compensation (blood money, i.e. Diya) be given to the deceased's family, unless they remit it. If the deceased belonged to a people at war with you and he was a believer; the freeing of a believing slave (is prescribed), and if he belonged to a people with whom you have a treaty of mutual alliance, compensation (blood money - Diya) must be paid to his family, and a believing slave must be freed. And whoso finds this (the penance of freeing a slave) beyond his means, he must fast for two consecutive months in order to seek repentance from Allah. And Allah is Ever All-Knowing, All-Wise. 92 The recompense for he who kills a believer deliberately is Gehenna (Hell), he is eternal there. Allah will be angry with him and will curse him and prepare for him a great punishment. 93 O you who believe! when you go to war in Allah's way, make investigation, and do not say to any one who offers you peace: You are not a believer. Do you seek goods of this world's life! But with Allah there are abundant gains; you too were such before, then Allah conferred a benefit on you; therefore make investigation; surely Allah is aware of what 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 in ranks standing before Him, forgiveness and mercy; surely God is All-forgiving, All-compassionate. 96
