He is invisible and there is no similarity between Him and His creatures.
That is Allah, your Lord! There is no god but He, the Creator of all things; then worship ye Him; and He hath power to dispose of all affairs. NO VISION CAN GRASP HIM. But His grasp is over all vision: He is above all comprehension, yet is acquainted with all things. “How have come to you, from your Lord, proofs (to open your eyes): IF ANY WILL SEE, IT WILL BE FOR (THE GOOD OF) HIS OWN SOUL; IF ANY WILL BE BLIND, IT WILL BE TO HIS OWN (HARM): I am not (here) to watch over your doings.”
The Holy Quran (6:102…104)

From the root b-t-n with the classical Arabic connotations: to be concealed, to lie hidden to penetrate into, to be inside.
Lord! O God of the heavens and of the great Throne! Our Lord and the Lord of everything! The One Who splits the seed and the date-stone! The one Who has revealed the Torah, the Gospel, and the Holy Qur’an!
I seek refuge with You against the evil of every being whose forelock is in Your Hands! Lord! You are the First; there is nothing before You! And You are the Last; there is nothing after You.
You are the Apparent; there is nothing beyond You, and You are the Hidden One; there is nothing that can reach You! I plead to You to pay our debts on our behalf, and to save us from [the humiliation of] want.
Supplication of Prophet (PBUH)
