And when they meet those who believe they say: We believe, and when they are alone one with another they say: Do you talk to them of what Allah has disclosed to you that they may contend with you by this before your Lord? Do you not then understand?

(As for) those of you who turned back on the day when the two armies met, only the Shaitan sought to cause them to make a slip on account of some deeds they had done, and certainly Allah has pardoned them; surely Allah is Forgiving, Forbearing.

A speaker from among them said: Do not slay Yusuf, and cast him down into the bottom of the pit if you must do (it), (so that) some of the travellers may pick him up.

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.
