Using the prayer of women with men as evidence for free mixing

Question:
Honorable Shaykh, may Allah grant you success. He says: Those who argue for the permissibility of free mixing cite the fact that women prayed with men, or with the Prophet (peace and blessings be upon him) and his Companions, and that there was no barrier or partition between them?

Answer:
The absence of a barrier or partition does not necessitate free mixing. Rather, the women had their own rows behind the men. The men’s rows were in front of them. This is the Sunnah of the Messenger (peace and blessings be upon him). He would deliver the sermon on the festival day; the men would listen, and when he finished, he would go to the women and deliver a sermon to them. This is evidence that they were not mixed with the men. This is a fallacy on the part of these people. It is a fallacy on their part.
Yes, they pray with the Muslims, but they are separated from the men. It is not a necessary consequence of that to build a wall or put up some barrier; that is not required. The important thing is their separation from the men. They do not stand beside a man or in the middle of the rows. They have their own rows. The Messenger (peace and blessings be upon him) said: , which indicates that the women have rows distinct from the rows of the men.
