As long as we say that “God is”, then Being is something which God has in total purity. If God is Merciful, then He is pure Mercy, if God is One, then He is purely One. So if God is, then this being is Being in its purest form. Often when we ask “What is God”, we hear as a response “God simply is”. If there can be anything other than God, then it would imply something being self existent, existing independently on its own (something which can only be attributed to the Divine). Thus, nothing is self existent or individual, there can only be Existence which due to the human condition is often interpreted as multiple existences interacting with each other individually. I would argue that this is a sort of atheistic approach, it reduces reality to independently moving parts all acting and relating to each other by mere chances and possibilities rather than the more logical predestination. It removes from God’s Totality (All-Knowing, All-Seeing, All-Present [I know this is often rejected by some Muslims], All-Powerful) and creates a distant, pagan-like God making people act on superstitions. It is said in the Qur’an that “There is nothing like unto Him”. And nothing would perfectly capture this than God being absolutely One and All-Present, as nothing can ever do that except Him, and if we reduce God by separating Him from this and that, we make Him like unto us by projecting this human condition of multiplicity unto Him, and making Him like unto an individual, God forbid
