My uncle says he believes in the unity of existence, and I have advised him. Should I boycott him for the sake of Allah while continuing to advise him?

Question:
He says: Honorable Shaykh, may Allah grant you success. I have an uncle who claims affiliation with a group of the Mu'tazilah (a rationalist theological sect) and says he believes in the unity of existence. I have advised him, and others have advised him as well. Should I boycott him for the sake of Allah while continuing to advise him, since I am afraid he will slip his ideas among my children? What should I do with him?

Answer:
His saying that he believes in the unity of existence is more severe than his leaning toward the Mu'tazilah or saying what the Mu'tazilah say. The Mu'tazilah are less severe than the belief in the unity of existence. Because the unity of existence is explicit disbelief. Explicit disbelief. It is uglier than the disbelief of Pharaoh. So long as that is the case, and you are certain that he adheres to this doctrine, you and your children should stay away from him. Stay away from him, you and your children. And if it is established against him that he says this, it is not permissible to leave him alone; the Shari'ah ruling must be applied to him if he is in a country where the Shari'ah ruling is applied. Yes.
