It is narrated from Hazrat Aisha (may Allah be pleased with her) that we recited the Talbiyah for Hajj, and when we reached the place of Sarif, my "periods" began. The Prophet (peace and blessings be upon him) came and I was crying. The Prophet (peace and blessings be upon him) said, "Aisha! Why are you crying?" I replied, "My 'periods' have started. I wish I had not come for Hajj." The Prophet (peace and blessings be upon him) said, "Subhan Allah! This is something Allah has decreed for all the daughters of Adam (peace be upon him). You should perform all the rites, except do not perform the Tawaf of the House (Ka'bah)." When we entered Makkah Mukarramah, the Prophet (peace and blessings be upon him) said, "Whoever wishes to change his Ihram to that of Umrah may do so, except for the one who has a sacrificial animal with him." And the Prophet (peace and blessings be upon him) slaughtered a cow on behalf of his wives on the tenth of Dhul-Hijjah. On the night of Batha, I became "pure" and said, "O Messenger of Allah! Will my companions return with both Hajj and Umrah, and I will return with only Hajj?" So the Prophet (peace and blessings be upon him) instructed Abdur Rahman bin Abi Bakr, and he took me to Tan'eem, from where I entered into Ihram for Umrah.
