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 And whoever slays a Muslim on purpose, his reward will be hell – to remain in it for ages – and Allah has wreaked wrath upon him and has cursed him and kept prepared a terrible punishment for him. 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 Muslims who stay back from holy war without proper excuse, are not equal to the Muslims who fight in Allah's cause with their wealth and lives; Allah has bestowed higher ranks to the warriors who strive with their wealth and lives, than those who stay back; and Allah has promised good to all; and Allah has favoured the warriors upon those who stay back, with a great reward. 95 Ranks (of honour) from Him, and forgiveness, and mercy; and Allah is Oft Forgiving, Most Merciful. 96
