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 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 you who have believed, when you go forth [to fight] in the cause of Allah, investigate; and do not say to one who gives you [a greeting of] peace "You are not a believer," aspiring for the goods of worldly life; for with Allah are many acquisitions. You [yourselves] were like that before; then Allah conferred His favor upon you, so investigate. Indeed Allah is ever, with what you do, Acquainted. 94 Those of the believers who sit still, other than those who have a (disabling) hurt, are not on an equality with those who strive in the way of Allah with their wealth and lives. Allah hath conferred on those who strive with their wealth and lives a rank above the sedentary. Unto each Allah hath promised good, but He hath bestowed on those who strive a great reward above the sedentary; 95 For them are higher ranks with God, and forgiveness and grace; and God is forgiving and kind. 96
