Boycotting students of knowledge by one another, by analogy to the Salaf boycotting the people of innovation

Question:
Honorable Shaykh, may Allah grant you success. This is a question from some of the students of knowledge. It says: The beginners who came to these blessed lands for the sake of seeking knowledge say, "We are students at the university, and we boycott one another on the pretext that the Salaf used to boycott the people of innovation. Also, we boycott everyone who did not boycott the other, and we speak about some of the other students and say, 'This is good backbiting, just as the Salaf did.'"

Answer:
You are seeking knowledge; you did not come to boycott one another and deny each other. If so, what is the benefit of seeking knowledge? Seek knowledge, and know that you are mistaken in this, and that they are your brothers. If they have an error short of shirk (associating partners with Allah) or kufr (disbelief), they are your brothers, your brothers in religion. Yes. And it is the right of a brother, the right of a brother, to maintain ties with him and to greet him, and every believer is your brother, even if he has a deficiency or sins or disobedience, as long as he has not reached the level of kufr (disbelief), he is your brother. Yes.
