Blessed be He in Whose hands is Dominion. And He over all things hath Power.
He Who created Death and Life, that He may try which of you is best in deed;
And He is the Exalted in Might, Oft-Forgiving.
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?
Again turn thy vision a second time; (thy) vision will come back to thee
dull and discomfited in a state worn out.

Qur'an 67,1-4.
