Musnad Abu Ya'la al-Mawsili 209:98

Abu Khaythama narrated to us, Abd al-Rahman narrated to us, from Malik, from Abu al-Aswad, from Urwah, from Zaynab bint Umm Salamah, from Umm Salamah: That she arrived while she was ill, so she mentioned that to the Prophet, peace and blessings of Allah be upon him. He said, "Perform the circumambulation (Tawaf) behind the people while you are riding." She said: I heard the Prophet, peace and blessings of Allah be upon him, while he was at the Kaaba, reciting "At-Tur."
