67:3
ٱلَّذِى خَلَقَ سَبْعَ سَمَٰوَٰتٍ طِبَاقًا مَّا تَرَىٰ فِى خَلْقِ ٱل رَّحْمَٰنِ مِن تَفَٰوُتٍ فَ ٱرْجِعِ ٱلْ بَصَرَ هَلْ تَرَىٰ مِن فُطُورٍ
[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?
