Pilgrimmage (Hajj)
Bukhari :: Book 2 :: Volume 26 :: Hadith 698
Narrated Um Salama:
I informed Allah's Apostle that I was sick. He said, "Perform Tawaf (of the Kaba) while riding behind the people." So, I performed the Tawaf while Allah's Apostle was offering the prayer beside the Kaba and was reciting Surat-at-Tur.
