Musnad Abu Ya'la al-Mawsili 149:6

'Abd al-A'la narrated to us, from Malik, from Abu al-Aswad Muhammad ibn 'Abd al-Rahman ibn Nawfal—who was an orphan under the guardianship of 'Urwah—from 'Urwah ibn al-Zubayr, from 'Aishah, that the Prophet (may Allah bless him and grant him peace) performed Hajj in isolation (ifrad).
