Surah Al-Mulk, Verse 3

ٱلَّذِي خَلَقَ سَبۡعَ سَمَٰوَٰتٖ طِبَاقٗاۖ مَّا تَرَىٰ فِي خَلۡقِ ٱلرَّحۡمَٰنِ مِن تَفَٰوُتٖۖ فَٱرۡجِعِ ٱلۡبَصَرَ هَلۡ تَرَىٰ مِن فُطُورٖ٣

alladhī khalaqa sabʿa samāwātin ṭibāqan mā tarā fī khalqi l-raḥmāni min tafāwutin fa-ir'jiʿi l-baṣara hal tarā min fuṭūrin

[And] who created seven heavens in layers. 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?
