It is not for a believer to kill another believer, except that it is by error. Whosoever kills a believer in error, let him free a believing slave, and ransom is to be handed to his family, unless they forgo being charitable. If he belonged to a people who are your enemies and is a believer then, the setting free of a believing slave. If he belonged to a people in which there is between you and them a treaty, then a ransom is to be handed to his family and the setting free of a believing slave. But, if he does not find (the means) let him fast two consecutive months in repentance to Allah. And Allah is the Knower, the 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 cause of God, make due investigation and do not say to those who offer you the greeting of peace, "You are no believer!" because you seek the good things of this life. With God there are good things in plenty. You yourself were in the same position before, but God conferred His special favour on you. Therefore, take care to investigate. Surely 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
