Thank you for your question. There are a number of definitions of the term wahdat al-wujud and to get a grasp on these definitions and what their implications are it is important to study theoretical 'irfan. Traditional Shii scholars would not accept something that contradicts the scriptural sources and so it is important to be clear which definition of wahdat al-wujud a certain scholar agrees with. Wujud in theoretical 'irfan means God, and wahdah means unity. Wahdat al-wujud therefore means the unity of God and so there is no scholar who would disagree with the unity of God. What is more important is what is meant by that unity, which is a technical issue that needs some introductory study.
May you always be successful
