All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
We do not know anything about this man, but with regard to these statements that are attributed to him, be it about Yazeed Ibn Mu’aawiyah, or the origin of the creation of grapes, or the person who consumes intoxicants, then we have not come across any source in the Sharee’ah about all these matters. Rather, they are nothing but lies and superstitions. These matters cannot be said by a man who can be called a Daa’iyah (a caller to Allaah). Therefore, if these statements are really attributed to this man, then it is not permissible to listen to him especially by the general public who cannot distinguish the truth from falsehood.
If a Muslim speaks about the Religion of Allaah, he should speak with knowledge, because it is very serious to attribute to religion that which is not part of it. Allaah Says (what means): {Indeed, those who invent falsehood about Allaah will not succeed.}[Quran 16:116-117]
Moreover, it is confirmed that the Prophet said: “Telling a lie about me is not like telling a lie about anyone else; whoever deliberately tells a lie about me, let him have his place in Hellfire.” [Al-Bukhari and Muslim]
Allaah Knows best.
