Hu
The eternal-constant being is Divine Light and infinite. Two infinite-everlasting beings are not possible. Just as the existence of Allah-the real being is compulsory, His absolute Oneness is also compulsory. Adam (Man)-Spirits and Angels, every being is Hu in reality. This is only in reality but not in identity. The identity-divinity of Allah is exempted from the Creation because He is the eternal, everlasting, omnipresent Existence. The other beings are nominal, temporary beings which manifest with the Existence of Allah same as the temporary foam on the sea. It must be remembered that the origin of foam is also sea. The foam have no real presence.
Allah is the existence of all the existed beings. He is the Being of the beings, the essence of beings and our essence. Hu is One. The unity of Allah is compulsory same as His existence. Allah does not impart His person to anybody and it cannot be imparted. His person is one and He cannot be divided and He has no sides. But, He imparts His other attributions of His names to the Creation and Adam.
“I taught Adam all My names.” (Quran:Baqhara, 31) Adam is the mirror of Allah’s Person and manifestation of His names-His attributions.
