[He] who created death and life to test you [as to] which of you is best in deed – and He is the Exalted in Might, the Forgiving – [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?
(Al-Mulk 67:2-3)
