The Ruling on the Faith of the People of the Book After the Prophet's Mission

Question:
May Allah reward you. Honorable Shaykh, this questioner says: Is it correct to say that among the People of the Book today there are people who believe in Allah and His Messenger, or was that only before the mission of the Prophet (peace and blessings be upon him)?

Answer:
Before the mission of the Prophet (peace and blessings be upon him), yes. After the mission of the Prophet, no one believes in Allah and His Messenger except one who follows this Messenger. "O mankind, indeed I am the Messenger of Allah to you all, to whom belongs the dominion of the heavens and the earth. There is no deity except Him, who gives life and gives death. So believe in Allah and His Messenger, the unlettered prophet who believes in Allah and His words, and follow him that you may be guided." This verse is decisive, because whoever does not obey the Messenger (peace and blessings be upon him) is a disbeliever, whether he is a Jew, a Christian, or whoever he is.
Because he is the only prophet until the Hour occurs. There is no prophet with him, and no prophet will come after him (peace and blessings be upon him). And the religion of Islam is the only religion; no other religion will ever come. Yes.
