The Ruling on Selling Books and Tapes That Contain Cursing

Question:
He says: Honorable Shaykh, may Allah grant you success, is it a form of deception to sell books and tapes that contain cursing of the Companions or cursing of the scholars, and what is the ruling on selling such things?

Answer:
This is forbidden; it is forbidden to sell them and forbidden to take their price. It is obligatory to destroy them; it is obligatory to collect them and destroy them, to render them worthless, because they contain falsehood. And whatever is false, it is forbidden to sell it, forbidden to buy it, and forbidden to keep it. Rather, it is obligatory to destroy it immediately. It is obligatory for the people of hisbah, or for the ministry, yes, the ministry responsible for these matters, to collect these tapes and books and burn them and destroy them, to ward off harm from the Muslims. And it is not permissible to promote them among the Muslims, yes.
