o Dawood ! surely We have made you a ruler in the land; so judge between men with justice and do not follow desire, lest it should lead you astray from the path of Allah; (as for) those who go astray from the path of Allah, they shall surely have a severe punishment because they forgot the day of reckoning.

So when you meet in battle those who disbelieve, then smite the necks until when you have overcome them, then make (them) prisoners, and afterwards either set them free as a favor or let them ransom (themselves) until the war terminates. That (shall be so); and if Allah had pleased He would certainly have exacted what is due from them, but that He may try some of you by means of others; and (as for) those who are slain in the way of Allah, He will by no means allow their deeds to perish.
