The Prophet (Peace and blessings be upon him) said, “Allah will take the whole earth (in His Hand) and will roll up the Heaven in His right Hand, and then He will say, “I am King! Where are the kings of the earth?
Sahih Bukhari [Volume 8, Book 76, Number 526]
Indeed, Allah knows the unseen [aspects] of the heavens and the earth. And Allah is Seeing of what you do.
"It is Allah who erected the heavens without pillars that you [can] see; then He established Himself above the Throne and made subject the sun and the moon, each running [its course] for a specified term. He arranges [each] matter; He details the signs that you may, of the meeting with your Lord, be certain." -Qur’an (13:3)
"Surely your Lord is Allah, Who created the heavens and the earth in six periods of time, and He is firm in power; He throws the veil of night over the day, which it pursues incessantly; and (He created) the sun and the moon and the stars, made subservient by His command; surely His is the creation and the command; blessed is Allah, the Lord of the worlds."
Most surely in the creation of the heavens and the earth and the alternation of the night and the day, and the ships that run in the sea with that which profits men, and the water that Allah sends down from the cloud, then gives life with it to the earth after its death and spreads in it all (kinds of) animals, and the changing of the winds and the clouds made subservient between the heaven and the earth, there are signs for a people who understand.
