وَجَعَلْنَا السَّمَاءَ سَقْفًا مَّحْفُوظًا وَهُمْ عَنْ آيَاتِهَا مُعْرِضُونَ
We made the sky a preserved roof and yet they are disregardful of its signs.
Agha Ali Puya Commentary
Commentary on Quran 21:32
[Pooya/Ali Commentary 21:32] The vast universe, containing innumerable cosmic systems bigger than the solar system, which appears like a canopy does not fall down, or its various components do not collide with each other, because it is well-guarded by laws made by Allah, yet those who disbelieve do not see the clear signs of Allah's power and go astray.
