Qur'an 67:3 · Al-Mulk

ٱلَّذِى خَلَقَ سَبْعَ سَمَٰوَٰتٍۢ طِبَاقًۭا ۖ مَّا تَرَىٰ فِى خَلْقِ ٱلرَّحْمَٰنِ مِن تَفَٰوُتٍۢ ۖ فَٱرْجِعِ ٱلْبَصَرَ هَلْ تَرَىٰ مِن فُطُورٍۢ

(3) [And] who created seven heavens in layers.[1712] 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?
