While we were praying (Jumua Khutba & prayer) with the Prophet ﷺ, some camels loaded with food, arrived (from Sham). The people diverted their attention towards the camels (and left the mosque), and only twelve persons remained with the Prophet. So this verse was revealed: "But when they see Some bargain or some amusement, They disperse headlong to it, And leave you standing." (62.11)  

بَيْنَمَا نَحْنُ نُصَلِّي مَعَ النَّبِيِّ ﷺ إِذْ أَقْبَلَتْ عِيرٌ تَحْمِلُ طَعَامًا فَالْتَفَتُوا إِلَيْهَا حَتَّى مَا بَقِيَ مَعَ النَّبِيِّ ﷺ إِلاَّ اثْنَا عَشَرَ رَجُلاً فَنَزَلَتْ هَذِهِ الآيَةُ {وَإِذَا رَأَوْا تِجَارَةً أَوْ لَهْوًا انْفَضُّوا إِلَيْهَا وَتَرَكُوكَ قَائِمًا}  

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 }  

Jabir b. Abdullah reported that the Apostle ﷺ was delivering the sermon on Friday in a standing posture when a caravan from Syria arrived. The people flocked towards it till no one was left (with the Holy Prophet) but twelve persons, and it was on this occasion that this verse in regard to Jumu'a was revealed." And when they see merchandise or sport. they break away to it and leave thee standing."  

أَنَّ النَّبِيَّ ﷺ كَانَ يَخْطُبُ قَائِمًا يَوْمَ الْجُمُعَةِ فَجَاءَتْ عِيرٌ مِنَ الشَّامِ فَانْفَتَلَ النَّاسُ إِلَيْهَا حَتَّى لَمْ يَبْقَ إِلاَّ اثْنَا عَشَرَ رَجُلاً فَأُنْزِلَتْ هَذِهِ الآيَةُ الَّتِي فِي الْجُمُعَةِ { وَإِذَا رَأَوْا تِجَارَةً أَوْ لَهْوًا انْفَضُّوا إِلَيْهَا وَتَرَكُوكَ قَائِمًا}  

While we were praying (Jumua Khutba & prayer) with the Prophet ﷺ, some camels loaded with food, arrived (from Sham). The people diverted their attention towards the camels (and left the mosque), and only twelve persons remained with the Prophet. So this verse was revealed: "But when they see Some bargain or some amusement, They disperse headlong to it, And leave you standing." (62.11) (Using translation from Bukhārī 936)  

بَيْنَمَا نَحْنُ نُصَلِّي الْجُمُعَةَ مَعَ رَسُولِ اللهِ ﷺ إِذْ أَقْبَلَتْ عِيرٌ تَحْمِلُ طَعَامًا قَالَ فَالْتَفَتُوا إِلَيْهَا حَتَّى مَا بَقِيَ مَعَ رَسُولِ اللهِ ﷺ إِلَّا اثْنَا عَشَرَ رَجُلًا فَنَزَلَتْ هَذِهِ الْآيَةُ {وَإِذَا رَأَوْا تِجَارَةً أَوْ لَهْوًا انْفَضُّوا إِلَيْهَا وَتَرَكُوكَ قَائِمًا} [الجمعة 11]
