It is not rightful for a Muslim to kill another Muslim, unless it occurs by mistake; and the one who mistakenly kills a Muslim must set free a Muslim slave and pay blood-money to the family of the slain, except if they forego it; and if the victim is of a people who are hostile to you, and the killer is a Muslim, then only the setting free of a Muslim slave (is obligatory); and if the victim is from a people between whom and you there is a treaty, then blood-money must be paid to his family and the setting free of a Muslim slave; therefore one who has no means must fast for two consecutive months; this is his penance before Allah; and Allah is All Knowing, Wise. 92 And whoever slays a Muslim on purpose, his reward will be hell – to remain in it for ages – and Allah has wreaked wrath upon him and has cursed him and kept prepared a terrible punishment for him. 93 O believers, when you are journeying in the path of God, be discriminating, and do not say to him who offers you a greeting, 'Thou art not a believer,' seeking the chance goods of the present life. With God are spoils abundant. So you were aforetime; but God has been gracious to you. So be discriminating; surely God is aware of the things you do. 94 Not equal are those believers remaining [at home] - other than the disabled - and the mujahideen, [who strive and fight] in the cause of Allah with their wealth and their lives. Allah has preferred the mujahideen through their wealth and their lives over those who remain [behind], by degrees. And to both Allah has promised the best [reward]. But Allah has preferred the mujahideen over those who remain [behind] with a great reward - 95 [many] degrees thereof and forgiveness of sins, and His grace; for God is indeed much-forgiving, a dispenser of grace. 96
