Was there a separation between men and women in the Prophet’s Mosque during the time of the Prophet (peace and blessings be upon him)?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Some people argue for the mixing of men and women by stating that it is not reported that there was a barrier between men and women in the Prophet’s Mosque during his time (peace and blessings be upon him). What is the response to them?

Answer:
But the women’s section does not require a barrier; they are separated. They are separated and pray behind the men.
And when the Prophet (peace and blessings be upon him) prayed in the house of Umm Sulaym, Anas said: I stood, along with an orphan, behind him, and Umm Sulaym stood behind us. I did not move from the Prophet’s position, and she became positioned behind the Prophet and behind them. This indicates the absence of mixing, in that the woman is always behind the men in prayer.
As for the Prophet’s Mosque, we were behind the men; we were not mixed with the men, and no barrier was needed. Until recently, there were no barriers, but the women were behind the men, isolated, covered, and veiled, so nothing of them was seen. Yes.
