Sayyidah Umm Salamah (may Allah be pleased with her) said: I complained to the Messenger of Allah (peace and blessings be upon him) of my illness, and he (peace and blessings be upon him) said: "Perform tawaf behind the people while riding." She said: So I performed tawaf, and at that time the Messenger of Allah (peace and blessings be upon him) was praying beside the House, reciting Surah al-Tur [Al-Tur: 1].

When Ibn Hisham prevented women from performing tawaf along with men, Ata (may Allah have mercy on him) said: "How can you prevent them when the wives of the Messenger of Allah (peace and blessings be upon him) performed tawaf?" I said: "Was that before (the command of) hijab or after?" He said: "By my life, I saw it after the hijab." I said: "How did they mix with the men?" He said: "They did not mix. Sayyidah Aishah (may Allah be pleased with her) would perform tawaf keeping apart from the men, not mingling with them. A woman said: 'O Mother of the Believers, come, let us touch (the Stone).' She said: 'You go yourself,' and she refused. They would go out at night, unrecognised, and perform tawaf with the men; but when they wanted to enter the House, they would stand and wait until they could enter, and the men would be taken out. Ubayd and I used to visit Sayyidah Aishah (may Allah be pleased with her) while she was staying in the hollow of Thabir." I said: "And what was her screen?" He said: "She was in a Turkish dome that had a covering; there was nothing between us and her other than that, and I saw a rose-coloured garment on her."
