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 And he who slays a believer wilfully his reward is Hell, where he will abide. Allah's wrath is against him and He has cast His curse upon him, and has prepared for him a great chastisement. 93 [Hence,] O you who have attained to faith, when you go forth [to war] in God's cause, use your discernment, and do not - out of a desire for the fleeting gains of this worldly life - say unto anyone who offers you the greeting of peace, "Thou art not a believer" for with God there are gains abundant. You, too, were once in the same condition - but God has been gracious unto you. Use, therefore, your discernment: verily, God is always aware of what you do. 94 Among the believers, those who stay at home without a good reason are not equal to those who strive for the cause of God in person or with their property. To those who strive for His cause in person or with their property, God has granted a higher rank than to those who stay at home. God has promised that everyone will receive his proper share of the reward but He will grant a much greater reward to those striving for His cause than to those who stay home (for no reason). 95 (High) degrees from Him and protection and mercy, and Allah is Forgiving, Merciful. 96
