Is it permissible to read books that contain religious innovations (bid'ah) and misguidance, taking the truth from them and leaving the falsehood?

Question:
May Allah reward you, Your Eminence, father. The questioner says: Are books that contain religious innovations (bid'ah) and doctrinal misguidance to be read, taking the truth from them and leaving the falsehood? Is this general for everyone, whether a layperson or otherwise? Or is this specific to students of knowledge who can distinguish between the truth and the falsehood?

Answer:
As stated at the end of the question, the innovator and the ignorant person are not permitted to read in books of scholarly disagreement, especially in matters of creed. As for the one who is well-established in knowledge and discerning, there is nothing wrong with him looking into them in order to know the truth from the falsehood, in order to be able to refute these people. So only the people of knowledge enter into them. Yes.
