question #3 Sahih Muslim 863d, Book 7, Hadith 50 : What significance do Abu Bakr and ‘Umar hold in the context of this event during the Friday sermon?

While the Messenger of Allah (ﷺ) was delivering (a sermon) on Friday, a caravan of merchandise came to Medina. The Companions of the Messenger of Allah (ﷺ) rushed towards it till only twelve persons were left with him including Abu Bakr and ‘Umar; and it was at this occasion that this verse was revealed.” And when they see merchandise or sport, they break away to it.”
