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 The recompense for he who kills a believer deliberately is Gehenna (Hell), he is eternal there. Allah will be angry with him and will curse him and prepare for him a great punishment. 93 O you who believe! When you go (to fight) in the Cause of Allah, verify (the truth), and say not to anyone who greets you (by embracing Islam): "You are not a believer"; seeking the perishable goods of the worldly life. There are much more profits and booties with Allah. Even as he is now, so were you yourselves before till Allah conferred on you His Favours (i.e. guided you to Islam), therefore, be cautious in discrimination. Allah is Ever Well-Aware of what you do. 94 The Muslims who stay back from holy war without proper excuse, are not equal to the Muslims who fight in Allah's cause with their wealth and lives; Allah has bestowed higher ranks to the warriors who strive with their wealth and lives, than those who stay back; and Allah has promised good to all; and Allah has favoured the warriors upon those who stay back, with a great reward. 95 Ranks specially bestowed by Him, and Forgiveness and Mercy. For Allah is Oft-forgiving, Most Merciful. 96
