(11) باب فِي قَوْلِهِ تَعَالَى: {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."
