Sahih Bukhari, Chapter: Pilgrimage (Hajj)

My father said, "(Before Islam) I was looking for my camel .." The same narration is told by a different sub-narrator. Jubair bin Mutim said, "My camel was lost and I went out in search of it on the day of 'Arafat, and I saw the Prophet standing in Arafat. I said to myself: By Allah he is from the Hums (literally: strictly religious, Quraish were called so, as they used to say, 'We are the people of Allah we shall not go out of the sanctuary). What has brought him here?"
