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 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 believers, when you go out on a journey in the way of God, be discreet and do not say to anyone who greets you in peace: "You are not a believer." You desire the gain of earthly life, but there are prizes in plenty with God. You were also like him (an unbeliever) in the past, but God has been gracious to you. So be careful and discreet, for God is aware of what you do. 94 SUCH of the believers as remain passive - other than the disabled - cannot be deemed equal to those who strive hard in God's cause with their possessions and their lives: God has exalted those who strive hard with their possessions and their lives far above those who remain passive. Although God has promised the ultimate good unto all [believers,] yet has God exalted those who strive hard above those who remain passive by [promising them] a mighty reward 95 in ranks standing before Him, forgiveness and mercy; surely God is All-forgiving, All-compassionate. 96
