Ash-Shu'ara 26:216–227

But if they, your kinsfolk, disobey you, say, to them: ‘I am absolved of what you do’, in worshipping [gods] other than God.

And put your trust (wa-tawakkal, or read fa-tawakkal, ‘then put your trust’) in the Mighty, the Merciful, God, in other words, entrust Him with all your affairs,

Who sees you when you stand, for prayer,

and your movements — in [performing] the [various] parts of prayer: standing, sitting, bowing and prostrating — among those who prostrate, those who perform the prayers.

Truly He is the Hearing, the Knowing.

Shall I inform you, O disbelievers of Mecca, upon whom the devils descend? (tanazzalu: one of the tā’ letters in the original [tatanazzalu] has been omitted).

They descend upon every sinful, profligate, liar, such as Musaylama and other soothsayers.

They, the devils, report the heard [sayings], what they hear from the angels [they report] to the soothsayers, but most of them are liars, adding much that is false to what they hear — this was [revealed] before the devils were barred from the heaven.

As for the poets, [only] the perverse follow them, in their poetry, propounding it and reciting it on their behalf to others; they are thus reprehensible.

Have you not noticed that — are you not aware that — in every valley, of the valleys of rhetoric and the art thereof, they rove, overstepping the bounds [of decency] in [their] eulogies and diatribes,

and that they say, we do, what they do not do?, in other words, that they lie.

Save those, poets, who believe and perform righteous deeds and remember God frequently, in other words, [those whom] poetry does not distract from the remembrance [of God], and vindicate themselves, by lampooning the disbelievers, after they have been wronged, by the disbelievers’ reviling of them [as belonging] together with all believers — such [individuals] are not reprehensible. God, exalted be He, says: God does not like the utterance of evil words out loud, unless a person has been wronged [Q. 4:148]; He, exalted be He, also says: so whoever commits aggression against you, commit aggression against him in the manner that he committed against you [Q. 2:194]; and those, poets and others, who are wrongdoers will soon know the reversal, the return, with which they will meet, [by which] they will return, after death.
