Overall meaning :
Allah Almighty provides some evidence that it is impossible for him to have a spouse or offspring. Addressing the idolaters of Makkah, He says: What! Has your Lord favoured you with sons and taken for Himself daughters from among the angels?! By making such a false claim, you are indeed saying a terrible thing. We have certainly explained the judgements, exhortations, parables and proofs in this Qur’an in various ways so that they may take heed, but this only makes them more averse to the truth and all the more heedless.
Say to them, Muhammad: Were there other gods besides Allah, as they falsely claim, these alleged gods would strive to find a way to worship Allah, seek His good pleasure and draw near to Him. How can they, then worship them? Limitless is He in His glory and sublimely exalted is He above what they say about Him!
The seven heavens, the earth and all the creatures in them declare His limitless glory. There is nothing that does not proclaim His limitless glory and praise, but you cannot comprehend their praises. Surely He is All-Forbearing—He does not hasten to inflict punishment on those who disobey Him—and All-Forgiving—He pardons those who repent and turn to Him.
