It is not for a believer to kill a believer unless (it be) by mistake. He who hath killed a believer by mistake must set free a believing slave, and pay the blood-money to the family of the slain, unless they remit it as a charity. If he (the victim) be of a people hostile unto you, and he is a believer, then (the penance is) to set free a believing slave. And if he cometh of a folk between whom and you there is a covenant, then the blood-money must be paid unto his folk and (also) a believing slave must be set free. And whoso hath not the wherewithal must fast two consecutive months. A penance from Allah. Allah is Knower, 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 Believers, if you march with arms for the cause of God, make sure that you know whom to fight. Do not accuse anyone who claims himself to be a Muslim of disbelief just for worldly gains. There is abundant bounty with God. Before, you were also like them, but God bestowed His favors upon you. Thus, make sure that you know whom to fight. God is Well Aware of what you do. 94 The holders back from among the believers, not having any injury, and those who strive hard in Allah's way with their property and their persons are not equal; Allah has made the strivers with their property and their persons to excel the holders back a (high) degree, and to each (class) Allah has promised good; and Allah shall grant to the strivers above the holders back a mighty reward: 95 high ranks conferred by Him as well as forgiveness and mercy. God is forgiving and merciful. 96
