God’s Essence, as stated in the Qur’an, is beyond the scope of human perception and comprehension. The human imagination cannot possibly conjure up what God is like. Imagination consists of fragments of reality already perceived; the human mind cannot imagine beyond what it sees and experiences in the physical world. The picture-making power of the mind is based on observation; God resembles or compares to nothing in this world.
God or No God by Haya Muhammad Eid
Ponder about the creatures of God and do not ponder about God Himself (His Essence) lest you be ruined.
Prophet Mohammad (PBUH)
Whatever mental picture you have of God, God is different.
Ibn Hanbal
