Yahya related to me from Malik from Abu'l-Aswad Muhammad ibn Abd ar-Rahman ibn Nawfal from Urwa ibn az-Zubayr from Zaynab bint Abi Salama that Umm Salama, the wife of the Prophet, may Allah bless him and grant him peace, said, "I once complained to the Messenger of Allah, may Allah bless him and grant him peace, that I was ill and he said, 'Do tawaf riding behind the people.' So I did tawaf riding my camel, while the Messenger of Allah, may Allah bless him and grant him peace, was praying by the side of the House, reciting Surat at-Tur."
