عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَدِمَتْ عِيرٌ مَرَّةً الْمَدِينَةَ وَرَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَخْطُبُ فَخَرَجَ النَّاسُ وَبَقِيَ اثْنَا عَشَرَ فَنَزَلَتْ {وَإِذَا رَأَوْا تِجَارَةً أَوْ لَهْوًا انْفَضُّوا إِلَيْهَا} (سورة الجمعة: 11)
Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates: Once a (trade) caravan arrived in Madinah Munawwarah while the Messenger of Allah (peace and blessings be upon him) was delivering a sermon. So the people stood up and left (the mosque), and only twelve men remained. At that time, this verse was revealed: "And when they see some merchandise or amusement, they rush towards it."
