A caravan arrived (at Medina) while we were offering the Jumua prayer with the Prophet. The people left out for the caravan, with the exception of twelve persons. Then this Verse was revealed: 'But when they see some bargain or some amusement, they disperse headlong to it and leave you standing." (62.11)
أَقْبَلَتْ عِيرٌ وَنَحْنُ نُصَلِّي مَعَ النَّبِيِّ ﷺ الْجُمُعَةَ فَانْفَضَّ النَّاسُ إِلاَّ اثْنَىْ عَشَرَ رَجُلاً فَنَزَلَتْ هَذِهِ الآيَةُ {وَإِذَا رَأَوْا تِجَارَةً أَوْ لَهْوًا انْفَضُّوا إِلَيْهَا وَتَرَكُوكَ قَائِمًا }
