Does not believing in God's intrinsic encompassment of all aspects of the universe invalidate a Muslim's faith, or is God's intrinsic encompassment of the universe not one of the necessities of religion?

A believer must be convinced that Allah is High above His creation and encompasses them in a manner befitting His majesty. The heavens and the earth in His hand are smaller than a chickpea in the hand of one of us.

Ibn al-Qayyim said that the gateway to knowing and worshipping Allah is to comprehend the Lord's encompassment of the universe and His greatness. All the worlds are in His grasp, and the seven heavens and seven earths are in His hand like a mustard seed in the hand of a servant.

For this reason, Allah associates the name Al-Ali (The Most High), indicating that He is manifest and that nothing is above Him, with the name Al-Adheem (The Most Great), indicating His encompassment and that nothing is beneath Him, as in His saying: "And He is the Most High, the Most Great" and "And He is the Most High, the Most Grand."

And He, glorified be He, is High above His creation by His essence, so there is nothing above Him. And He is hidden by His essence, so there is nothing beneath Him. Rather, He is manifest over everything, so He is above it, and He is hidden, so He is closer to everything than its own self. And He encompasses it, and everything is in His grasp.
