QS. Al-Mulk [67:3]

alladzii khalaqa sab'a samaawaatin thibaaqan maa taraa fii khalqi alrrahmaani min tafaawutin farji'i albashara hal taraa min futhuurin

[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? [3]
