May Allah reward you, Your Eminence, father. The questioner asks: Is it permissible for a Muslim to boycott his Muslim brother if he disagrees with him on certain issues on which the scholars differ, such as not declaring the one who abandons prayer to be a disbeliever,

The Shaykh:
or what?

The questioner:
He says: You have received questions like not declaring the one who abandons prayer to be a disbeliever, or some doubtful issues?

The Shaykh:
In the disputed jurisprudential issues that have evidence and a possibility of interpretation, boycotting is not permissible. Boycotting is not permissible. The Companions and those who came after them differed on jurisprudential issues, yet they did not become hostile to one another, nor did they boycott one another. This is the action of the ignorant. This is the action of the ignorant. Yes.
