The Prophet (blessings and peace of Allah be upon him) was very keen that women should not mix with men even in the mosque, and the entire community adhered to this refined Islamic etiquette. Umm Salamah, the wife of the Prophet (blessings and peace of Allah be upon him) narrates that at the time of the Messenger of Allah (blessings and peace of Allah be upon him), when the women said the taslim at the end of the obligatory prayer, they would get up [to leave the mosque], and the Messenger of Allah (blessings and peace of Allah be upon him) would remain in his place after they got up. The men who had prayed with him would also remain for as long as Allah willed, then when the Messenger of Allah (blessings and peace of Allah be upon him) got up, the men also got up. This was lest the men mix with the women. In congregational prayers, the women’s rows were at the back, with the children’s rows in front of them, and in front of the children were the men’s rows, behind the Prophet (blessings and peace of Allah be upon him). This hadith indicates that the imam should pay attention to the circumstances of those praying behind him, and he should take measures to avoid any situation that could lead to impropriety. It indicates that one should avoid being in any dubious situation in which one could be accused of mischief. It indicates that men should not mix with non-mahram women in the streets, let alone in houses..
