Is the narration of the fifth tier, who are the young of the Tabi'un, connected, even though hearing from the Companions has not been established for some of them?

The questioner : May Allah reward you. Here, too, among the questions, on page five of al-Taqrib, it states that they are the young of the Tabi'un, and that if they saw one or two of the Companions, but hearing from the Companions has not been established for some of them, like al-A'mash. The question is: Is their narration connected? Is their narration considered connected if he saw, meaning narrated from, a Companion?

The Shaykh : Establishing the sighting does not necessitate establishing the narration.

The questioner : Yes, meaning it may be disconnected in this case.

The Shaykh : Disconnected, yes.

The questioner : Disconnected.

The Shaykh : Yes.

The questioner : But his statement that "hearing has not been established for some of them" indicates, by implication, that some of them did hear.

The Shaykh : So if some of them did hear, at that time.

The questioner : And he stated it explicitly.

The Shaykh : Yes.

The questioner : Yes, if Allah wills.
