The problem of people splitting up because they follow one shaykh over another?

Question:
This questioner says: May Allah reward you. We are from Britain, and we see a great trial (fitnah) that has spread, and its root is the discord between two shaykhs. It started between them, and we see two parties of Muslims: one party with one shaykh and another party with the other shaykh. This is not specific to London; we have this issue of splits and divisions here as well, and each side attacks the other. This is a trial (fitnah).

Answer:
I ask Allah to protect the Muslims from it. It is obligatory for the students of knowledge to advise one another, to reconcile, to make peace among themselves, and to cooperate in righteousness and piety. This discord is from Shaytan, and those who assist Shaytan in his call to misguidance are the ones who incite the youth to these matters and spread them among them until what happened occurs, or something worse. It is obligatory for the students of knowledge to advise one another, to cooperate, and to reconcile if a misunderstanding occurs between them. Yes.
