The Ruling on Errors in Methodology and Boycotting for Them

Question:
May Allah reward you. Is it permissible to boycott a person who has errors in his methodology?

Answer:
Boycott him. But the methodology now, we do not know; the youth have divided into groups, and each one declares the other misguided. What is the methodology? Is it the methodology of the Mu'tazilah, the Khawarij, and the people of misguidance? Yes, that person is boycotted.
Or is it a methodology where you assumed it was a methodology of misguidance, but it is not misguidance, meaning there was a misunderstanding between you and him, or he did what you asked and you said, "This is a bad methodology; it must be corrected." The methodologies are the methodology of truth and the methodology of the people of misguidance. Whoever is on the methodology of the people of misguidance is joined with them and attacked, whether Khawarij, Mu'tazilah, Shi'ah, or Rafidah. And whoever is on the methodology of the people of truth, the people of the Sunnah and the community, he is encouraged, supplicated for, and supported. This is the difference between the two. As for imagined methodologies, just because they did not agree with what you want, you say, "This is a bad methodology." It is not befitting for the brothers to have these matters between them without verification of this issue. Show us that these people are on the methodology of the people of misguidance, and we will boycott them, us and you. And show us that these people are on the methodology of truth, and we will join them, us and you. But mere things in the hearts, this requires verification, O servants of Allah. We do not want division among us, nor do we want incitement between the Muslims, nor do we want anything but clarity and proof. Yes.
