Al-Mulk - 67:3

الَّذِي خَلَقَ سَبْعَ سَمَاوَاتٍ طِبَاقًا مَّا تَرَى فِي خَلْقِ الرَّحْمَنِ مِن تَفَاوُتٍ فَارْجِعِ الْبَصَرَ هَلْ تَرَى مِن فُطُورٍ
[67:3]
Who created the seven heavens one above another; you see no incongruity in the creation of the Beneficent Allah; then look again, can you see any disorder?
He Who created the seven heavens one above another: No want of proportion wilt thou see in the Creation of (Allah) Most Gracious. So turn thy vision again: seest thou any flaw?
Who hath created seven heavens in harmony. Thou (Muhammad) canst see no fault in the Beneficent One's creation; then look again: Canst thou see any rifts?
