Is it permissible to continue benefiting from an Islamic preacher who is rumored to be Qubaysiyah, with her followers increasing?

It is not permissible to alienate people from a preacher who enjoins good and forbids evil with knowledge and insight, and who is steadfast upon the methodology of the People of the Sunnah (definition) and the Community, unless he deviates from this methodology after being advised and persisting in his deviation. Judging individuals and groups requires consulting trustworthy scholars, while being cautious not to categorize people based on mere conjecture, due to the harms therein. Instead, one should busy themselves with beneficial knowledge, righteous deeds, and dawah within the sphere of women.
