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 Any one who kills a believer intentionally will be cast into Hell to abide there for ever, and suffer God's anger and damnation. For him a greater punishment awaits. 93 O believers, when you go out on a journey in the way of God, be discreet and do not say to anyone who greets you in peace: "You are not a believer." You desire the gain of earthly life, but there are prizes in plenty with God. You were also like him (an unbeliever) in the past, but God has been gracious to you. So be careful and discreet, for God is aware of what you 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 high ranks conferred by Him as well as forgiveness and mercy. God is forgiving and merciful. 96
