Surah Al-Mulk — Ayah 3 (67:3)
ٱلَّذِي خَلَقَ سَبۡعَ سَمَٰوَٰتٖ طِبَاقٗاۖ مَّا تَرَىٰ فِي خَلۡقِ ٱلرَّحۡمَٰنِ مِن تَفَٰوُتٖۖ فَٱرۡجِعِ ٱلۡبَصَرَ هَلۡ تَرَىٰ مِن فُطُورٖ ٣
English translation (Saheeh International)
[And] who created seven heavens in layers.1 You do not see in the creation of the Most Merciful any inconsistency. So return [your] vision [to the sky]; do you see any breaks?
- - i.e., one covering or fitting over the other.
Brief commentary
The one who created the seven heavens, each one layered above the one before it without touching it. O observer! You will not witness any discrepancy or misappropriation in the creation of Allah. So look again, do you see cracks or splits? You will never see them; you will only see a perfect, masterful creation.
