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.
