Is warning people about those who believe in the sons of the righteous considered backbiting?

Question:
His last question says: If I have warned some people about individuals who say, "We are the sons of shaykhs," or "We are the sons of awliya (close friends of Allah)," and they believe that the sons of the righteous, while they are still alive, am I a backbiter or a talebearer; because the verse says: [Al-Hujurat: 12]?

The Shaykh: Repeat.

The presenter: He says: If you have warned people about individuals who say, "We are the sons of shaykhs," or "We are the sons of awliya (close friends of Allah)," and they believe that the sons of the righteous, while they are still alive, are you a backbiter or a talebearer; because the verse says: [Al-Hujurat: 12]?

Answer:
And they believe in the sons of the righteous?

The presenter: Yes: Yes, they believe in the sons that they are from the sons of the righteous, and that they....

The Shaykh: In any case, religion is sincere advice. The Prophet (peace and blessings be upon him) said: So if you see some people deviating from the truth and calling to falsehood, whether they call themselves shaykhs, or call themselves awliya (close friends of Allah), or they attribute themselves to shaykhs and awliya (close friends of Allah), then you warn your brothers from these people; so that they do not mislead them. This is not from the category of backbiting, nor from the category of talebearing, but it is from the category of sincere advice for the sake of Allah and His servants. So the one who gives sincere advice is not called a backbiter. When Fatimah bint Qays came to the Prophet (peace and blessings be upon him) saying, "O Messenger of Allah, so-and-so has proposed to me, and so-and-so has proposed to me," he gave her sincere advice and said to her: meaning: a man who beats women So he gave her sincere advice, and this was not backbiting, even though he named them, saying: so-and-so and so-and-so, Mu'awiyah and Abu Jahm.
The point is: that the Messenger (peace and blessings be upon him) gave her sincere advice, and explained to her that these two men are not suitable for her, and suggested Usamah ibn Zayd to her. This indicates that the one who gives sincere advice is not called a backbiter or a talebearer. He tells you: Do not approach so-and-so, do not sit with so-and-so; because he does such and such, and I fear for you from him. There is no blame in this if the intention is sincere advice and fear for him from evil. Yes.
