It is not for a believer to kill a believer except (that it be) by mistake, and whosoever kills a believer by mistake, (it is ordained that) he must set free a believing slave and a compensation (blood money, i.e. Diya) be given to the deceased's family, unless they remit it. If the deceased belonged to a people at war with you and he was a believer; the freeing of a believing slave (is prescribed), and if he belonged to a people with whom you have a treaty of mutual alliance, compensation (blood money - Diya) must be paid to his family, and a believing slave must be freed. And whoso finds this (the penance of freeing a slave) beyond his means, he must fast for two consecutive months in order to seek repentance from Allah. And Allah is Ever All-Knowing, All-Wise. 92 If a man kills a believer intentionally, his recompense is Hell, to abide therein (For ever): And the wrath and the curse of Allah are upon him, and a dreadful penalty is prepared for him. 93 Believers, when you go forth in the cause of God, make due investigation and do not say to those who offer you the greeting of peace, "You are no believer!" because you seek the good things of this life. With God there are good things in plenty. You yourself were in the same position before, but God conferred His special favour on you. Therefore, take care to investigate. Surely God is well-aware of what you 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 Degrees of rank from Him, and forgiveness and mercy. Allah is ever Forgiving, Merciful. 96
