Sahih Muslim Book - 7, Hadith - 1997

حَدَّثَنَا عُثْمَانُ بْنُ أَبِى شَيْبَةَ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ كِلاَهُمَا عَنْ جَرِيرٍ - قَالَ عُثْمَانُ حَدَّثَنَا جَرِيرٌ - عَنْ حُصَيْنِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ سَالِمِ بْنِ أَبِى الْجَعْدِ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ أَنَّ النَّبِىَّ -صلى الله عليه وسلم- كَانَ يَخْطُبُ قَائِمًا يَوْمَ الْجُمُعَةِ فَجَاءَتْ عِيرٌ مِنَ الشَّامِ فَانْفَتَلَ النَّاسُ إِلَيْهَا حَتَّى لَمْ يَبْقَ إِلاَّ اثْنَا عَشَرَ رَجُلاً فَأُنْزِلَتْ هَذِهِ الآيَةُ الَّتِى فِى الْجُمُعَةِ (وَإِذَا رَأَوْا تِجَارَةً أَوْ لَهْوًا انْفَضُّوا إِلَيْهَا وَتَرَكُوكَ قَائِمًا)

It was narrated from Jabir bin 'Abdullah that the Prophet (s.a.w) was delivering the Khutbah standing one Friday, when a caravan came from Ash-Sham. The people went towards it until there were only twelve men left, then this verse which is in Surat Al-Jumu'ah was revealed: "And when they see some merchandise or some amusement they disperse headlong to it, and leave you standing."
