Question: If a student of knowledge falls into some mistakes, and his ʿaqīdah is generally sound, is it obligatory upon us to hate and warn against him?

Shaykh Ṣāliḥ ibn Fawzān al-Fawzān

Advise him. It may be that he is ignorant or doesn’t know. Clarify and advise him. If he persists upon [his mistakes] then hate him in accordance to the level of his deviation.
