باب فِي الْوُقُوفِ وَقَوْلِهِ تَعَالَى ‏{‏ ثُمَّ أَفِيضُوا مِنْ حَيْث أَفَاضَ النَّاسُ}

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 (ﷺ) 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.
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَمْرٌو النَّاقِدُ، جَمِيعًا عَنِ ابْنِ عُيَيْنَةَ، - قَالَ عَمْرٌو حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، - عَنْ عَمْرٍو، سَمِعَ مُحَمَّدَ بْنَ جُبَيْرِ بْنِ مُطْعِمٍ، يُحَدِّثُ عَنْ أَبِيهِ، جُبَيْرِ بْنِ مُطْعِمٍ قَالَ أَضْلَلْتُ بَعِيرًا لِي فَذَهَبْتُ أَطْلُبُهُ يَوْمَ عَرَفَةَ فَرَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَاقِفًا مَعَ النَّاسِ بِعَرَفَةَ فَقُلْتُ وَاللَّهِ إِنَّ هَذَا لَمِنَ الْحُمْسِ فَمَا شَأْنُهُ هَا هُنَا وَكَانَتْ قُرَيْشٌ تُعَدُّ مِنَ الْحُمْسِ ‏.‏
