Believers in God including Christian believe God is great to the extent, it's not possible to be greater. They believe greatness, goodness, beauty, honor, love, exist in absolute sense. But this makes sense only if we see God as One indivisible reality. In fact, saying he can a trinity or divisions can exist within himself, or that he can have aspects, would open room for other gods to exist with him. What makes fifty gods the same as God's greatness, belittle his greatness in what way? If he can have trinity and be one, why can't there be infinite amount of absolute gods. The reason is simple. It lies in the emphasized name "The life/the living/the existence/the existing". The absolute great is such that all life is his and such that nothing could exist "with" the absolute life, but it's one, and not multiple. Had God has many aspects or parts, each aspect or part would not be absolute life and ultimate reality, and hence he would be formed of non-absolute attributes. But he is such that his names described himself, and his attributes are all about one perfect absolute essence and reality and sheer existence, and are not describing divisions.
Had this not been the case, and absolute existence can be formed of aspects, divisions or parts, then by logic, how does saying another god exists with God violate his greatness? If he can have a son, he can infinite sons. If he can be begotten, then there can be infinite dependent gods.
It's for this reason Suratal Ikhlaas/Tawheed starts with:
With/through/by the name of God, the Compassionate, the Merciful, say God is One/single.
Here it means God is sheer existence. It then follows he neither begets nor is begotten, because such beings would be dependent on God while God is independent (Samad).
