Quadim human

How many people in the Islamic Ghulāt sects believe that there is one singular quadīm being/person that takes human form, born form a woman, who lived forever without begining?

Many people claimed Abu Ali al-Mansur, better known by his regnal name al-Hakim bi-Amr Allah, was Allah incarnate.

Many people believe that the future Mahdi will be God incarnate, or will have the fullness of God’s diety dwelling in him, fully divine- quadīm.

So how many people believe either muhhamad, a previous imam/person or the future Mahdi will be quadīm- and that he was/will be the one and only quadīm human

And unity of spirit with this one single quadīm human is required to enter eternal life in paradise?

As I said, many many people claimed this about that one dude I mentioned. This is a prevalently held belief that Allah has or will take human form

And that unity of spirit with this perfect quadīm human is required to enter eternal life
