And never is it for a believer to kill a believer except by mistake. And whoever kills a believer by mistake - then the freeing of a believing slave and a compensation payment presented to the deceased's family [is required] unless they give [up their right as] charity. But if the deceased was from a people at war with you and he was a believer - then [only] the freeing of a believing slave; and if he was from a people with whom you have a treaty - then a compensation payment presented to his family and the freeing of a believing slave. And whoever does not find [one or cannot afford to buy one] - then [instead], a fast for two months consecutively, [seeking] acceptance of repentance from Allah. And Allah is ever Knowing and Wise. 92 The punishment for one who purposely slays a believer will be to live in hell fire forever. God is angry with him and has condemned him. He has prepared for him a great torment. 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 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 God will grant those who strive high ranks, forgiveness, and mercy. He is All-forgiving and All-merciful. 96
