(My personal view on the issue.)
Allah (the exalted) described himself as Most High and Above All in many place in Qur'an.
Allah - there is no deity except Him, the Ever-Living, the Sustainer of [all] existence. Neither drowsiness overtakes Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that can intercede with Him except by His permission? He knows what is [presently] before them and what will be after them, and they encompass not a thing of His knowledge except for what He wills. His Kursi extends over the heavens and the earth, and their preservation tires Him not. And He is the Most High, the Most Great. (Ayat Al-Kursi)
This ayah is one of the most memorized ayah in Qur'an and given much importance in Islam. (youYou can open seperate question about Ayat al-Kursi). In this ayah it is mentioned that Allah (the exalted) is the sustainer of all existence and the owner of it. So this would suggest that Allah (the exalted) is above the universe, and not the universe itself.
A revelation from He who created the earth and highest heavens, The Most Merciful [who is] above the Throne established.To To Him belongs what is in the heavens and what is on the earth and what is between them and what is under the soil. (Surat Ţāhā 4-6)
Surat taha starts by mentioning that Qur'an is a revelation from Allah (the exalted) who created the universe, and mentions that he is the owner of everything.
There are much more ayah in Qur'an mentioning that Allah (the exalted) created the universe, he is sustaining it, and he is the owner of it. I would conclude that Islam isn't compatible with pantheism.
