Al-Mulk 67:3

Who created seven heavens one above another; you will not see any imperfection[1] in the creation of the Most Compassionate. Look again; can you see any flaw?

[1] All parts of the universe are well connected and in perfect harmony and coordination. There is no indiscipline, disorder and discordance in the universe, and nothing is disjointed and out of proportion in the creation of Allah. As for birth defects, genetic mutations and other things that we see in the world are part of this great creation, for perfection cannot be noticed except if the opposite is seen, also as a test for humans.

[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?

[1712] i.e., one covering or fitting over the other.

3. Who has created the seven heavens one above another; you can see no fault in the creation of the Most Gracious. Then look again: "Can you see any rifts?"

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?
