Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
Bukhari :: Book 6 :: Volume 60 :: Hadith 376
Narrated Um Salama:
I complained to Allah's Apostle that I was sick, so he said, "Perform the Tawaf (of Ka'ba at Mecca) while riding behind the people (who are performing the Tawaf on foot)." So I performed the Tawaf while Allah's Apostle was offering the prayer by the side of the Ka'ba and was reciting: 'By the Mount (Saini) and by a Decree Inscribed.'
