It is not for a believer to slay another believer unless by mistake. And he who has slain a believer by mistake, his atonement is to set free from bondage a believing person and to pay blood-money to his heirs, unless they forgo it by way of charity. And if the slain belonged to a hostile people, but was a believer, then the atonement is to set free from bondage a believing person. And if the slain belonged to a (non-Muslim) people with whom you have a covenant, then the atonement is to pay the blood-money to his heirs, and to set free from bondage a believing person. But he who cannot (free a slave) should fast for two consecutive months. This is the penance ordained by Allah. Allah is All-Knowing, All-Wise. 92 If a man kills a believer intentionally, his recompense is Hell, to abide therein (For ever): And the wrath and the curse of Allah are upon him, and a dreadful penalty is prepared for him. 93 O People who Believe! When you go forth to fight in holy war, make a proper study, and do not say to the one who greets you, “You are not a Muslim,” – you seek the means of this worldly life; so with Allah are the bounties in plenty; you too were like this before, then Allah bestowed His favour on you, therefore you must make a proper study; indeed Allah knows whatever you do. 94 The holders back from among the believers, not having any injury, and those who strive hard in Allah's way with their property and their persons are not equal; Allah has made the strivers with their property and their persons to excel the holders back a (high) degree, and to each (class) Allah has promised good; and Allah shall grant to the strivers above the holders back a mighty reward: 95 Degrees [of high position] from Him and forgiveness and mercy. And Allah is ever Forgiving and Merciful. 96
