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 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 Believers, if you march with arms for the cause of God, make sure that you know whom to fight. Do not accuse anyone who claims himself to be a Muslim of disbelief just for worldly gains. There is abundant bounty with God. Before, you were also like them, but God bestowed His favors upon you. Thus, make sure that you know whom to fight. God is Well 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
