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 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 way of Allah, discern (between friend and foe), and do not say to him who offers you the greeting of peace: 'You are not a believer.' If you seek the good of this worldly life, there lies with Allah abundant gain. After all, you too were such before, and then Allah was gracious to you. Discern, then, for Allah is well aware of what you do. 94 Believers who stay behind, having no injury, are not equal to those who fight in the way of Allah with their wealth and their souls. Allah has preferred those who fight with their wealth and their souls a degree above those who stay behind (because of sickness). Yet to each, Allah has promised the most excellent (Paradise). And Allah has preferred those who fought over those who stayed behind with a great wage. 95 (High) degrees from Him and protection and mercy, and Allah is Forgiving, Merciful. 96
