You Desire Protection? Then Do Not Lend An Ear To Ahlul Bidah [Rationalists and Philosophers Disguised as Muslim Intellectuals and advisers during times of Fitan]
Muhammad Ibn Nadr Al-Haarithee (rahimahullaah) said:
Whoever lends an ear to a person of bidah, whilst being aware that he (i.e. such a person) is a person of bidah, then protection is removed from him (i.e. the listener) and he is entrusted to himself.
