Narrated Muhammad bin Jubair bin Mut`im:

My father said, "(Before Islam) I was looking for my camel .." The same narration is told by a different sub-narrator. Jubair bin Mut`im said, "My camel was lost and I went out in search of it on the day of `Arafat, and I saw the Prophet (ﷺ) 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?"

Narrated `Urwa:

During the Pre-Islamic period of Ignorance, the people used to perform Tawaf of the Ka`ba naked except the Hums; and the Hums were Quraish and their offspring. The Hums used to give clothes to the men who would perform the Tawaf wearing them; and women (of the Hums) used to give clothes to the women who would perform the Tawaf wearing them. Those to whom the Hums did not give clothes would perform Tawaf round the Ka`ba naked. Most of the people used to go away (disperse) directly from `Arafat but they (Hums) used to depart after staying at Al-Muzdalifa. `Urwa added, "My father narrated that `Aisha had said, 'The following verses were revealed about the Hums: Then depart from the place whence all the people depart--(2.199) `Urwa added, "They (the Hums) used to stay at Al-Muzdalifa and used to depart from there (to Mina) and so they were sent to `Arafat (by Allah's order)."
