Was Lady Aisha sitting with the Companions in the presence of the Messenger (peace be upon him), or do the wives of the Messenger (peace be upon him) have a special case regarding intermingling?

The Companions heard the hadith from Aisha, may Allah be pleased with her, either from behind a veil, as in the narration of Abu Salama and Masruq, or they were her relatives, such as Ibn Al-Zubayr and Urwah, or women would convey the hadith to their husbands. The Mothers of the Believers observed hijab after the revelation of the verse: "And when you ask them for something, ask them from behind a partition."
