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 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 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
