Regarding The Books, Gatherings And Speech Of Innovators

Shaykh Shams Ad-Deen Aboo Muhammad Ibn Muflih said, “Shaykh Muwaffaq Ad-Deen (i.e. Ibn Qudaamah), may Allaah have mercy upon him, mentioned the forbiddance of looking into the books of innovators. He said:

‘The Salaf used to forbid others from sitting with the innovators, looking into their books, and listening to their speech.’ “
