Islam is monotheistic religion ( and so does Christianity and Judaism claim to be ) in which God is eternal , all powerful and all knowing , its is independent on any thing even to its attribute

there are multiple verse like below ; which would partially intersect with Pantheistic belief ( if I understood it correctly)

https://islam.stackexchange.com/questions/35046/is-islam-a-pantheistic-religion

"He is the apparent and the hidden" (57:3), verse that if literally understood, implies that God is virtually everything because all things are either apparent like the natural universe or hidden such as angels, so we can summarize the verse by saying "He is everything" or "He is the creation".

"He is with you wherever you be"(57:4) and "We are closer to him than his vein"?! (50:16) The question that these verses raise is that how God can always accompany us and be closer to us than our vein without becoming subject to time and space or becoming part of the creation? (Also see What is the concept of holool [sic] in Sufism?)

I think true religion is one which explain all the meta question ( good, evil, human, connection of human to universe, ..) provide answers to both physical and meta-physicals questions , provide meaning, give path way to human to create a balance between themselves and community and natures ; based of justice , equality, freedom ; make human responsible and active and owner of this universe like a guardian ( instead of being lazy, depressed and oppressed) and remove human from slavery of all humans to the slavery of only the God ; basically make human action oriented and agent of change as God is ( by being the creator of every thing)

Also I can argue that every religion started as monotheistic until there followers turned it into some thing else
