And We have not instructed him poetry, nor is it meet for him.(36:69)

While the fifteenth sentence points to the verse:

Were there gods other than God in the heavens and earth, there surely would have been confusion in both.(21:22)

You can make further examples from the other sentences like these. It is like this: it says at the start: Announce the divine decrees. You are not a soothsayer, for the words of soothsayers are confused and conjectural, while yours are true and certain. And you are not mad; your enemies even attest to your perfect sanity.

Or do they say: A poet – let us wait and see what time will do!(52:30)

Do they call you a poet, like the unreasoning, common infidels? Are they waiting for you to perish? You say to them: “Wait! I shall wait with you!” Your vast and brilliant truths are free of the imaginings of poetry and independent of their fancies.

Or is it that their faculties of understanding urge them to this?(52:32)

Or like unreasoning philosophers who rely on their reasons, do they hold back from following you, saying: “Our faculties of reason are sufficient.” But reason commands that you are followed, because everything you say is reasonable. But again the reason on its own cannot reach it.

Or are they but a people transgressing all bounds?(52:32)

Or is the reason for their denial their not submitting to Almighty God like wicked tyrants? But the ends are known of the Pharaohs and Nimrods, who were the leaders of arrogant oppressors.

Or do they say: He fabricated this [Message]? Nay, they do not believe.(52:33)

Or like lying dissemblers without conscience do they accuse you saying: “You have made up the Qur’an!”? But up to this time they have known you to be the most truthful among them and have called you Muhammad the Trustworthy. It means that they have no intention to believe. Otherwise let them find the like of the Qur’an among the works of men.

Or were they created of nothing?(52:35)

Or like the absurd philosophers who believed the universe to be without purpose and in vain, do they suppose themselves to be aimless and without wisdom, purpose, duty, or Creator? Have they become blind that they do not see that the universe is adorned from top to bottom with instances of wisdom and bears the fruit of aims, and that beings from particles to the suns are charged with duties and are subjugated to the divine commands?
