Musnad Ahmad 1153:1298

Ibn Numayr narrated to us, 'Abd al-Malik narrated to us, from 'Ata', from 'A'ishah, who said: I said, "O Messenger of Allah, will your wives return with a Hajj and an 'Umrah, while I return with a Hajj that has no 'Umrah with it?" So the Messenger of Allah, peace and blessings of Allah be upon him, stayed for her at al-Batha'. He commanded her, and she went out to al-Tan'im, and her brother 'Abd al-Rahman ibn Abi Bakr went out with her. She entered into the state of Ihram for an 'Umrah, then she came to the House (the Ka'bah), performed Tawaf around it and between al-Safa and al-Marwah, and shortened her hair. Then he slaughtered a cow on her behalf.
