What did the Prophet Muhammad (peace be upon him) pray and recite while Um Salama was performing the Tawaf?
 Narrated Um Salama:                     I complained to Allah's Apostle that I was sick. He told me to perform the Tawaf behind the people while riding. So I did so and Allah's Apostle was praying beside the Ka`ba and reciting the Sura starting with "Wat-tur wa kitabin mastur."
