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 But whoever kills a believer intentionally - his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great 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 The faithful who sit idle, other than those who are disabled, are not equal to those who fight in the way of God with their wealth and lives. God has exalted those in rank who fight for the faith with their wealth and souls over those who sit idle. Though God's promise of good is for all, He has granted His favour of the highest reward to those who struggle in preference to those who sit at home. 95 Ranks (of honour) from Him, and forgiveness, and mercy; and Allah is Oft Forgiving, Most Merciful. 96
