Who Recommends Reading the Books of the Callers to Misguidance

Question:
Honorable Shaykh, what is your opinion of one who claims tawhid (the oneness of Allah) and recommends reading the books of callers to misguidance?

Answer:
One who recommends reading the books is certainly doing so to refute them, if he recommends reading them to distinguish the truth from falsehood, in order to refute them, then there is no harm, on the condition that the one who reads is, as he says, knowledgeable, knowing the truth from falsehood. But if he recommends reading them because he approves of what is in them, then he is a caller to misguidance, may Allah protect us from that, and it is not permissible to obey him or to seek his guidance.
