Is it true that if a session of knowledge is held, the session is not concluded with (Subhanaka Allahumma wa bihamdika ashhadu an la ilaha illa anta astaghfiruka wa atubu ilayk)?

The questioner : Abu Bakr al-Jaza'iri, one of the brothers, asked him why he does not say at the end of the session: Subhanaka Allahumma wa bihamdika ashhadu an la ilaha illa anta astaghfiruka wa atubu ilayk. He told him that as long as it is a session of knowledge, it is not said in it.

The Shaykh : May Allah guide him. The hadith says that if it was a session of good, it was like a seal, and otherwise it was an expiation.

The questioner: May Allah reward you with good.
