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 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 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 Not equal are those believers who sit (at home) and receive no hurt, and those who strive and fight in the cause of Allah with their goods and their persons. Allah hath granted a grade higher to those who strive and fight with their goods and persons than to those who sit (at home). Unto all (in Faith) Hath Allah promised good: But those who strive and fight Hath He distinguished above those who sit (at home) by a special reward,- 95 Ranks from Him and forgiveness and mercy; and Allah is ever Forgiving, Merciful. 96
