Narrated Jabir (RA):

Allah's Messenger (ﷺ) was standing while delivering the Khutbah (religious talk, sermon) on Friday when a caravan from Syria arrived. The people flocked towards it till no one was left [with the Prophet (ﷺ)] except twelve men. [Reported by Muslim].

وَعَنْ جَابِرٍ { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-كَانَ يَخْطُبُ قَائِمًا, فَجَاءَتْ عِيرٌ مِنَ اَلشَّامِ, فَانْفَتَلَ اَلنَّاسُ إِلَيْهَا, حَتَّى لَمْ يَبْقَ إِلَّا اثْنَا عَشَرَ رَجُلًا } رَوَاهُ مُسْلِمٌ .‏ [1]‏ .‏
