It belongs not to a believer to slay a believer, except it be by error. If any slays a believer by error, then let him set free a believing slave, and bloodwit is to be paid to his family unless they forgo it as a freewill offering. If he belong to a people at enmity with you and is a believer, let the slayer set free a believing slave. If he belong to a people joined with you by a compact, then bloodwit is to be paid to his family and the slayer shall set free a believing slave. But if he finds not the means, let him fast two successive months -- God's turning; God is All-knowing, All-wise. 92 And whosoever slayeth a believer intentionally, His meed is Hell, as an abider therein; and Allah shall be wroth with him and shall curse him, and shall get ready for him a torment terrible. 93 O ye who believe! When ye go abroad in the cause of Allah, investigate carefully, and say not to any one who offers you a salutation: "Thou art none of a believer!" Coveting the perishable goods of this life: with Allah are profits and spoils abundant. Even thus were ye yourselves before, till Allah conferred on you His favours: Therefore carefully investigate. For Allah is well aware of all that ye do. 94 Not equal are those believers remaining [at home] - other than the disabled - and the mujahideen, [who strive and fight] in the cause of Allah with their wealth and their lives. Allah has preferred the mujahideen through their wealth and their lives over those who remain [behind], by degrees. And to both Allah has promised the best [reward]. But Allah has preferred the mujahideen over those who remain [behind] with a great reward - 95 in ranks standing before Him, forgiveness and mercy; surely God is All-forgiving, All-compassionate. 96
