The ruling on using the term "master" for a disbeliever

Question:
He says: Honorable Shaykh, may Allah grant you success, is it permissible to address a disbeliever president, for example, as "Your Excellency, Master President So-and-So," or should we limit this title of excellence and mastery to his people? For instance, we say "Master of the Americans," just as it was said "Great One of the Romans" or "Emperor of the Romans"?

Answer:
The Prophet (peace and blessings be upon him) said, "Do not say to the hypocrite, 'O Master,' for if you do that, and he is indeed a master, you have angered your Lord." Therefore, it is not permissible to say "O Master" to a disbeliever, because this is an address of exaltation. As for saying "Master of the Americans" or "Master of such-and-such," I do not know about this; I have no information on it. Yes.
