أَخْبَرَنَا مُحَمَّدُ بْنُ قُدَامَةَ، قَالَ حَدَّثَنِي جَرِيرٌ، عَنْ مُطَرِّفٍ، عَنِ الشَّعْبِيِّ، عَنْ عُرْوَةَ بْنِ مُضَرِّسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أَدْرَكَ جَمْعًا مَعَ الإِمَامِ وَالنَّاسِ حَتَّى يُفِيضَ مِنْهَا فَقَدْ أَدْرَكَ الْحَجَّ وَمَنْ لَمْ يُدْرِكْ مَعَ النَّاسِ وَالإِمَامِ فَلَمْ يُدْرِكْ " .
