Faatir • EN-TAFSIR-MAARIF-UL-QURAN
﴿ ۞ إِنَّ ٱللَّهَ يُمْسِكُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ أَن تَزُولَا ۚ وَلَئِن زَالَتَآ إِنْ أَمْسَكَهُمَا مِنْ أَحَدٍۢ مِّنۢ بَعْدِهِۦٓ ۚ إِنَّهُۥ كَانَ حَلِيمًا غَفُورًۭا ﴾
“Verily, it is God [alone] who upholds the celestial bodies and the earth, lest they deviate [from their orbits] - for if they should ever deviate, there is none that could uphold them after He will have ceased to do so. [But,] verily, He is ever-forbearing, much-forgiving!”
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.
