Jubair. b. Mut'im reported: I lost my camel and went in search of it on the day of 'Arafa, and I saw the Messenger of Allah (may peace be upon him) staying along with people in 'Ara'fit. Thereupon I said: By Allah, he is among the Hums (Quraish) ; what has happened to him that he has come to this (place)? The Quraish were counted among Hums.
