It is not for a believer to slay another believer unless by mistake. And he who has slain a believer by mistake, his atonement is to set free from bondage a believing person and to pay blood-money to his heirs, unless they forgo it by way of charity. And if the slain belonged to a hostile people, but was a believer, then the atonement is to set free from bondage a believing person. And if the slain belonged to a (non-Muslim) people with whom you have a covenant, then the atonement is to pay the blood-money to his heirs, and to set free from bondage a believing person. But he who cannot (free a slave) should fast for two consecutive months. This is the penance ordained by Allah. Allah is All-Knowing, 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 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 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 high ranks conferred by Him as well as forgiveness and mercy. God is forgiving and merciful. 96
