Indeed, Allāh holds the heavens and the earth, lest they cease. And if they should cease, no one could hold them [in place] after Him. Indeed, He is Forbearing and Forgiving.
(Show Me what they have created of the earth. Or have they any share in the heavens) meaning, they have nothing at all of that, they do not possess even the membrane covering the stone of a date.
(Or have We given them a Book, so that they act on clear proof therefrom) meaning, `have We revealed to them a Book on which they base their Shirk and disbelief' This is not the case at all.
In the expression: إِنَّ اللَّـهَ يُمْسِكُ السَّمَاوَاتِ (Undoubtedly, Allah holds back the heavens and the earth - 35:41), the 'holding' of the heavens or the skies does not mean that their movement was stopped. Instead, it means holding them from moving askance - as the word: أَن تَزُولَا (an tazula: from leaving their existing state,) bears it out. Therefore, in this verse, there exists no supporting evidence on either side as to the skies move or they are static.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 41–42
The creation of the universe, with its unlimited space and the innumerable astronomical bodies suspended in it, is an awe-inspiring phenomenon. Such colossal creation—an unimaginally gigantic feat—cannot be wholly or even partially attributed to any of the beings whom people worship as deities. The fact is that worship of entities other than God is entirely based on fraudulence. Such practices will continue only till Doomsday, for on that Day, they will vanish as if they had never existed.
