I want to ask the Islamic view on Wahdatul Wujood (Pantheism).

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

The ideology of pantheism is an ideology of Kufr.  The above statement is deducted from the meaning of this ideology.  Its

practitioners say that the creator and creation coexist together as one.

They do not affirm the existence of the creator separate from the creation, as one being created by the other.  But they say that the creator is the creation and the creation is the Creator.  This is, of course, Kufr, according to all the scholars of Islam, because Allah is firmly established as above His creation.

Allah knows best.
