Keep Away From Ahlul Bidah [Rationalists and Philosophers Disguised as Muslim Intellectuals and advisers during times of Fitan]
Shaikh Hamood At-Tuwayjiree (rahimahullaah) said:
Indeed the Salaf As-Saaleh (pious predecessors) used to warn against ahlul bidah and they were severe in warning against them. They forbade (others) from listening to their speech; (forbade others) from sitting with them and (forbade others) from accompanying them.
