Does the obscurity of a narrator's status disappear when reliable narrators report from a narrator who has not been authenticated?

The questioner : My Shaykh, here is a matter in terminology: if no one has authenticated his status, he is called one whose status is unknown.The Shaykh: Yes.

The questioner : Okay, does the narration of two reliable narrators from him remove the obscurity from him, or how do we say it?

The Shaykh : This varies depending on the status of the narrators from him. For example, I said: Yahya ibn Sa'id al-Qattan narrated from him, but the second narrator from him is Marwan ibn Mu'awiyah, who engages in tadlis (concealment of a defect in a chain) of the shaykhs, meaning he changes the names of the shaykhs. So we no longer have confidence that this man narrated from two reliable narrators or more, so he remains one whose status is unknown.

The questioner : I mean, does the obscurity of the status disappear with the narration of two reliable narrators or more, my Shaykh?

The Shaykh : How?

The questioner : I say we understand that the obscurity of the status disappears.

The Shaykh : With three.

The questioner : With three.

The Shaykh: Yes.
