Advice for students of knowledge regarding brotherhood and avoiding discord among themselves

Question:
May Allah reward you, Your Eminence, father. The questioner says: It has become widespread among students of knowledge to lack cheerfulness toward one another, and this is after the groups entered these lands, out of fear that a student might belong to a specific group. What is your advice and guidance regarding this?

Answer:
This is wrong and not permissible. You are all brothers, and praise be to Allah, you are all Muslims and brothers. Your creed is one; there is no difference among you in creed. As for you belonging to such-and-such and him belonging to such-and-such, there is nothing wrong with the creed; it is all the creed of tawhid (the oneness of Allah), it is all a sound creed. So you are brothers. If you differ in some matters, and the disagreement does not reach the level of disagreement in creed, this is tolerated. As for disagreement in creed, it is not tolerated. As for disagreement that is less than disagreement in creed, it is not tolerated among brothers. Yes.
