Does one who believes someone’s claim to knowledge of the unseen become a disbeliever?

Question:
The Honorable Shaykh, may Allah grant you success, says regarding the words of the Exalted: He says, may Allah preserve you, that one who claims knowledge of the unseen is a disbeliever and is among the heads of the taghut (tyrants). Yes. The question is: does one who believes this taghut in his claim to knowledge of the unseen become a disbeliever by virtue of that belief?

Answer:
Yes, if he knows that the claimant is a liar and that he is lying, then he becomes a disbeliever like him, because he agreed with the disbelief. Yes. But if he is ignorant and does not know, then it is explained to him; he is informed and it is clarified for him. If he then persists and remains in his belief of the one who claims knowledge of the unseen, he is a disbeliever. Yes.
