What is the authenticity of this hadith: (There will be thirty liars in my Ummah, all of whom will claim to be a prophet)?

The questioner:
May Allah reward you, Honorable Shaykh. This questioner asks: How authentic is this hadith approximately thirty?

The Shaykh:
It is close to an athar: There will be thirty liars in my Ummah, all of whom will claim to be a prophet. This is in the book of Tawhid by Shaykh Muhammad ibn 'Abd al-Wahhab. Yes.

The questioner:
And in his question he asks: Is the number limited to these, or are they more?

The Shaykh:
No, it is not limited, but there will be thirty among them about whom the Prophet (peace and blessings be upon him) informed, and it is not restricted to this number. Yes.
