What is the guidance for one whom Allah has granted knowledge and who has many students of knowledge, but he wants to travel to learn from the scholars?

Question:
He says: Honorable Shaykh, may Allah grant you success. A man whom Allah has granted much knowledge and good, right? A man whom Allah has granted much knowledge and good, and in his country he has many students of knowledge, and a private institute for seeking knowledge in that country. He says he now wants to travel here, to this blessed land, to increase his knowledge from the great scholars. The question is: what do you advise him to do, may Allah preserve you?

Answer:
By Allah, if his staying with his students and in his country is better, he stays, and he can acquire knowledge by any means, by asking questions or reading books. But if his coming to acquire knowledge is better, he comes. Yes.
