The opponents of the Quran are like the devil who deceives man then quits himself from him:
There is an example of such people who spread antagonistic propaganda with their lies and deceit: they are to man like the devil who bids man to disbelieve then when man disbelieves, the Devil quits himself of him.
So God cited a parable of
Balaam and
King Balaq who deceived Balaam until he disbelieved then when he was in danger, King Balaq disowned him and both the king and Balaam went to Hell.
So
rational people who think and reason should not listen to the suggestions of such devils among mankind or else they will lose, as did Balaam lose when he listened to the suggestions of King Balaq.
Quran 59: 16-17, which mean:
{
16. Like the devil m when he said to man n: "Be ungrateful [to the grace of your Lord! o]"
Then when [Balaam] became a disbeliever p, [King Balaq] said: "I am quit of you q; for surely I fear [that] God, the Lord of the worlds [may punish me r.]"
17. So their end is, both [the king and Balaam] are in the Fire, therein dwelling forever; such is the rewarding of wrong-doers s. }

o And pray God for destruction of the Children of Israel.
It means: He invited him to an act including the disobedience of God’s command, then when he obeyed the command of the king and disobeyed the command of God, he became a disbeliever and ungrateful.
16
p And the Children of Israel came to fight them and defeat them, Balaam came to the king seeking about his protection and to rescue him from the Children of Israel and save him from the killing.
16
q Because you did not avert the might of the Children of Israel from me, neither did you guide me to the right and to the submission to them and to make peace with them; so that we might have been safe of the killing in the life of the World and from the punishment in the Next Life, had you guided me to the monotheism and to worship God alone.
16
r On account of what I did.
Afterwards, the Children of Israel captured and killed them both.
17
s Who wrong and deceive people with their lies and deception, and who lead them to destruction.
