Surely they who deviate from the right way concerning Our communications are not hidden from Us. What! is he then who is cast into the fire better, or he who comes safe on the day of resurrection? Do what you like, surely He sees what you do.

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.
