Boycotting those who insult scholars and rulers, and sitting with them

Question:
He also asks, saying: Some of the brothers who are studying at the university insult the scholars and rulers of Syria. Should we boycott them, not greet them, and not sit with them, or should we sit with them and mix with them since we know their ideas?

Answer:
Do not sit with them, and as for their speech, it is upon them. They harm the rulers of Saudi Arabia and harm no one but themselves. Yes. Their affairs are not your concern. The messengers spoke about them. They spoke about the messengers, especially our Prophet Muhammad (peace and blessings be upon him), and what Allah mentioned about him and what came in the hadiths and the Prophetic biography was said about him. And despite this, patience and relief—this is the obligatory duty of the Muslim: not to rush in such matters. The poet says: If the fool speaks, do not answer him, for the best of answers to him is silence. Yes.
