The claim that the Prophet failed in his call in al-Ta'if is disbelief and apostasy

Question:
We say: Honorable Shaykh, may Allah grant you success, what is the ruling on one who, while preaching to people, says that the Prophet (peace and blessings be upon him) failed in his call in al-Ta'if?

Answer:
We ask Allah for well-being. This is apostasy and disbelief. This is disbelief, may Allah protect us from it. The Messenger (peace and blessings be upon him) did not fail in calling the people of al-Ta'if; rather, he established the proof against them and conveyed the message of his Lord. Yes. And the people of al-Ta'if later became Muslims; they later became Muslims. That is, they responded to Allah and the Messenger, became Muslims, and among them were scholars, and among them were commanders in jihad, and among them were… so the call of the Messenger (peace and blessings be upon him) did not fail.
