Did Al-Husayn Start Wahdat ul-Wujud?
Shaykh Muhammad Bazmul says the claim that al-Husayn ibn Ali invented Wahdat ul-Wujud is a lie. He was a noble companion and would never promote such a belief. Wahdat ul-Wujud is rejected by scholars as a form of disbelief.
Questioner:
Some people say that the one who invented the idea of Waḥdat ul-Wujūd (Singularity of Existence or Panentheism) was al-Ḥusayn ibn `Aliyy ibn Abī Ṭālib, Allāh be pleased with him. What is your reply to this claim?
Shaykh Muḥammad Bāzmūl:
This is a lie and a libel against al-Ḥusayn ibn `Aliyy ibn Abī Ṭālib, the grandson of the Messenger . We know of no heretical misguided statements that can be confirmed to have been made by any of the disciples, Allāh be pleased with them. Al-Ḥusayn ibn `Aliyy is the last person, in shā Allāh , who would make such a statement.
This, then, is a slander that we will not accept from the slanderer, and we turn it back on him, declare him a liar and warn people to be on their guard against him, because the idea of Waḥdatul Wujūd is an idea that the scholars all agree is a form of unbelief. All the scholars agree that it is a form of unbelief and a false notion.
