During the Pre-Islamic period of Ignorance, the people used to perform Tawaf of the Kaʿba 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 Kaʿba naked. Most of the people used to go away (disperse) directly from ʿArafat but they (Hums) used to depart after staying at Al-Muzdalifa. ʿUrwa added, "My father narrated that ʿAisha had said, 'The following verses were revealed about the Hums: Then depart from the place whence all the people depart--(2.199) ʿUrwa added, "They (the Hums) used to stay at Al-Muzdalifa and used to depart from there (to Mina) and so they were sent to ʿArafat (by Allah's order)."  

عُرْوَةُ كَانَ النَّاسُ يَطُوفُونَ فِي الْجَاهِلِيَّةِ عُرَاةً إِلاَّ الْحُمْسَ وَالْحُمْسُ قُرَيْشٌ وَمَا وَلَدَتْ وَكَانَتِ الْحُمْسُ يَحْتَسِبُونَ عَلَى النَّاسِ يُعْطِي الرَّجُلُ الرَّجُلَ الثِّيَابَ يَطُوفُ فِيهَا وَتُعْطِي الْمَرْأَةُ الْمَرْأَةَ الثِّيَابَ تَطُوفُ فِيهَا فَمَنْ لَمْ يُعْطِهِ الْحُمْسُ طَافَ بِالْبَيْتِ عُرْيَانًا وَكَانَ يُفِيضُ جَمَاعَةُ النَّاسِ مِنْ عَرَفَاتٍ وَيُفِيضُ الْحُمْسُ مِنْ جَمْعٍ قَالَ وَأَخْبَرَنِي أَبِي عَنْ عَائِشَةَ ؓ أَنَّ هَذِهِ الآيَةَ نَزَلَتْ فِي الْحُمْسِ {ثُمَّ أَفِيضُوا مِنْ حَيْثُ أَفَاضَ النَّاسُ} قَالَ كَانُوا يُفِيضُونَ مِنْ جَمْعٍ فَدُفِعُوا إِلَى عَرَفَاتٍ  

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

أَضْلَلْتُ بَعِيرًا لِي فَذَهَبْتُ أَطْلُبُهُ يَوْمَ عَرَفَةَ فَرَأَيْتُ النَّبِيَّ ﷺ وَاقِفًا بِعَرَفَةَ فَقُلْتُ هَذَا وَاللَّهِ مِنَ الْحُمْسِ فَمَا شَأْنُهُ هَا هُنَا
