The ruling on warning against the one being asked about if there are errors and mistakes in his writings

The questioner : Shaykh, may Allah bless you. Regarding this, there are some people who actually come, for example, the Shaykh asks him about some words from a book by another Shaykh, and he does not mention the name of that Shaykh. In that speech, it is, for example, general speech, so that Shaykh answers him regarding that speech. But is it permissible for the Shaykh being asked to warn against this man, against the speech of this man, like this without knowing? From the speech.

The Shaykh : No, not the man who said this speech without knowing.

The questioner : From the questioner.

The Shaykh : No, not the one being asked about.

The questioner : Fine, from the speech.

The Shaykh : From the owner of the speech, for example, he warns against the speech, saying that this speech is invalid and that it is not upon...

The questioner : Here he spoke about the speech.

The Shaykh : And he warns against it, the same man.

The questioner : No, he does not speak about the man; he says, "Whoever said such and such, one must beware of him."

The Shaykh : Meaning, he does not repeat it.
