SECTION: 13

92. And it is not befitting Muslims to shed the blood of Muslim save by a mischance and he who kills any Muslim unknowingly, then he has to free a Muslim slave and blood compensation to be paid to the family of the deceased but that they forego. Then if he is from a people who is your enemy and he is himself a Muslim then there is only the freeing of a Muslim slave, and if he is from a people between whom and you there is a pact, then the blood compensation be delivered to his family and the freeing of a slave Muslims, but whose hand does not reach to this (Finds no means to free a slave Muslim) then he should fast for two consecutive months this is his repentance near Allah. And Allah is knowing. Wise.

93. And whoso kills a Muslim wilfully, then his recompense is Hell, abiding therein for a long time and Allah's wrath is upon him and has cursed him and has prepared for him a great torment.

94. O believers! When you march forth for a crusade then make proper investigation and he who greets you, say not to him, 'you are not Muslim, you seek the goods of living world, then with Allah there are spoils abundant. You too were such before, and then Allah conferred His favour on you; so you are duty bound to investigate. Undoubtedly, Allah is aware of what you do.
