As Salaamu 'Alaikum,
Throughout the scriptures, particularly the Bible and Qur'aan, God (Allah) is described in many different ways. Some of these descriptions imply that the God of the Bible and Qur'aan is a living, breathing Human, simply being One Who has surpassed our current level of intelligence and power.
For example, the Biblical book of Genesis says that Allah ("Eloheim") made Man in His image and likeness, and based on many lexicons, this is specifically referring to God's physical attributes, implying the idea that Man LOOKS LIKE God. This thought is also conveyed in the ancient Hebrew Mischna, where the angels are described as nearly mistaking the first man (i.e. "Adam") for Allah Himself! The book of Psalms refers to God as having a physical body, and "ha' eloheim" (the gods) is used separately from "Eloheim" (God), Who is the highest One among them. Psalms 82:6 even goes to the point of saying that we are ALL "eloheim, benee' Elyon", or 'gods, sons of the Most High (God). This concept was also expressed in ancient Egyptian, Sumerian, and Babylonian literature and writings. Their god is ALWAYS depicted as having a physical form.
Now, when it comes to the Qur'aan, these attributes are expressed differently. According to Dr. D.B MacDonald's article on 'Allah' in the Encyclopedia of Islam, the descriptions of God in the Qur'aan are a "strange combination of anthropomorphism and metaphysics". Many passages directly imply that He is an anthropomorphic deity, having the physical embodiment of a Man. For example, Allah is mentioned as saying to Iblis:
"O Iblis, what prevented thee from submitting to him whom I created with MY TWO HANDS (bi-yadayya)?" (Q. 38:75)
People say that the "hand" of God is a metaphorical description of His power and might. However, what of TWO HANDS? This sounds like a physical description. This is further implied in 5:64, which says:
"And the Jews say, 'The hand of Allah is tied up.' Their own hands are shackled and they are cursed for what they say! Nay, BOTH HIS HANDS ARE SPREAD OUT." (Q. 5:64)
On top of this, the Qur'aan specifically mentions Allah as having a face and eyes, and He is said to have a soul (nafs):
Thou (God) knows what is in my soul (nafs), and I know not what is in Thy soul (nafs). (Q. 5:116)
He has decreed mercy from His soul (nafs). (Q. 6:112)
In addition, Allah is never specifically regarded as being omnipresent. In fact, the Qur'aan repeatedly mentions Him sitting on an 'arsh, or a physical throne. The seat of the king is considered an 'arsh.
There are many more examples I could mention, but these, in my opinion, are fairly sufficient. So, this brings forth the question, Who is this God? The Qur'aan itself reveals this. It says that the angels, along with all the believers submit and prostrate (i.e. 'sudja) to Allah alone. The problem? It specifically says that the angels bowed to the one whom Allah shaped with His two hands, after Allah blew His "ruch" (spirit/self) into Him. Here, it implies that Allah is actually INSIDE the Man who He created, and the angels were instructed to prostrate to this one. The one who refused was "Iblis", who was banished for his refusal. Why? It's because, in doing this, Iblis was refusing to prostrate to Allah Himself, Who was inhabiting this Man (body). This means, at a minimum, that part of God was dwelling inside the original Man on this planet, which is why the Man was considered to be Allah's "khalifa"/successor on this planet. In other words, he was formed to represent God on Earth, to be the lord and controller of it.
Is it possible that Allah could be a physical Person, the Supreme of beings?
