What is the correct legal position regarding the fatwa issued by the Sharia Committee of Ansar al-Sharia in Tunisia, which prohibits attending Muhammad Hassan's lectures and re-praying behind him?

The website is not concerned with judging individuals or groups, but rather with clarifying legal rulings. It has become clear to us that the prohibition of attending lectures by the mentioned preacher and praying behind him is invalid, as this ruling is not based on sound and clear evidence. The evidence mentioned in the statement is patently false and indicates the ignorance of its author and his recklessness in issuing rulings, especially regarding excommunication, which is a dangerous and deviant path. These people should be advised to verify information and refer to trustworthy scholars. Muslims should cooperate in goodness, offer mutual advice, and be vigilant against what their enemies intend for them. There is no objection to advising preachers who are not infallible, but dealing with errors must be done with a sound methodology that conforms to Islamic law.
