No believer should kill another believer, unless it be by mistake. Anyone who kills a believer by mistake should free a believing slave and pay blood money to the victim's relatives unless they forego it as an act of charity. If the victim belongs to a people at war with you, but is a believer, then the compensation is to free a believing slave. If he belongs to a people with whom you have a treaty, then blood-money should be handed over to his relatives and a believing slave set free. Anyone who lacks the means must fast for two consecutive months. Such is the penance imposed by God. God is all knowing and wise. 92 If anyone kills a believer deliberately, his reward shall be eternal Hell. God will condemn him and reject him, and prepare for him a terrible 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
