Bukhari

Ibn Juraij said, " 'Ata informed us that when Ibn Hisham forbade women to perform Tawaf with men he said to him, 'How do you forbid them while the wives of the Prophet (saws) used to perform Tawaf with the men ?' I said, 'Was this before decreeing of the use of the veil or after it ? 'Ata took an oath and said, 'I saw it after the order of veil.' I said, 'How did they mix with the men?' 'Ata said, 'The women never mixed with the men, and 'Aishah used to perform Tawaf separately and never mixed with men. Once it happened that 'Aishah was performing the Tawaf and woman said to her, 'O Mother of believers! Let us touch the Black stone.' 'Aishah said to her, 'Go yourself,' and she herself refused to do so. The wives of the Prophet (saws) used to come out in night, in disguise and used to perform Tawaf with men. But whenever they intended to enter the Ka'bah, they would stay outside till the men had gone out. I and 'Ubaid bin 'Umair used to visit 'Aishah while she was residing at Jauf Thabir." I asked, "What was her veil?" 'Ata said, "She was wearing and old turkish veil, and that was the only thing (weal) which was screen between us and her. I saw a pink cover on her."

Narrated Um Salama: (the wife of the Prophet) I informed Allah's Apostle that I was ill. So he said, "Perform the Tawaf while riding behind the people." I did so, and at that time the Prophet was praying beside the Ka`ba and reciting Surat-at-Tur.
