A believer cannot slay another believer except by mistake for which the retaliation is to set free a believing slave and pay the appointed blood money to the relatives of the deceased unless the relatives wave aside the payment. If the person slain is from your enemies but himself is a believer, the penalty is to set free a believing slave. If the person slain is one of those with whom you have a peace treaty, the penalty is the same as that for a slain believer. If this is not possible, the defendant has to fast for two consecutive months, asking God to accept his repentance. He is All-knowing and All-wise. 92 And whoever kills a believer intentionally, his punishment is hell; he shall abide in it, and Allah will send His wrath on him and curse him and prepare for him a painful chastisement. 93 O ye who believe! When ye go abroad in the cause of Allah, investigate carefully, and say not to any one who offers you a salutation: "Thou art none of a believer!" Coveting the perishable goods of this life: with Allah are profits and spoils abundant. Even thus were ye yourselves before, till Allah conferred on you His favours: Therefore carefully investigate. For Allah is well aware of all that ye do. 94 Those believers who sit at home, unless they do so out of a disabling injury, are not the equals of those who strive in the way of Allah with their possessions and their lives. Allah has exalted in rank those who strive with their possessions and their lives over those who sit at home; and though to each Allah has promised some good reward, He has preferred those who strive (in the way of Allah) over those who sit at home for a mighty reward. 95 [many] degrees thereof and forgiveness of sins, and His grace; for God is indeed much-forgiving, a dispenser of grace. 96
