The Profound meaning of the Oneness of God’s existence.
Many people define Oneness as God is one and not two and it has been discussed among the sayings of Amirul Mominin explaining these verses. This explanation of Oneness is incorrect because it means His Oneness if numerical (A second entity cannot be imagined with God but He does not have a material existence). Surely this is incorrect and the right thing will be to say, God is one and none other can be imagined with Him, in other words there is no similitude or replica of God and He is not like anything else because he has a unique and infinite existence.
We find a Hadith of Imam Jafar Sadiq (AS) asking his student the meaning of “God is great”. The person answered “God is greater than all things”. The Imam asked, “Is there any thing like Him compared to which He is greater?” The companion said, “then what is the meaning of “God is great”?” the Imam said, “God is far above to be described in any sense.” (1)
