حَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ، أَخْبَرَهُ أَنَّهُ، أَقْبَلَ يَسِيرُ عَلَى حِمَارٍ وَرَسُولُ اللَّهِ صلى الله عليه وسلم قَائِمٌ يُصَلِّي بِمِنًى فِي حَجَّةِ الْوَدَاعِ يُصَلِّي بِالنَّاسِ - قَالَ - فَسَارَ الْحِمَارُ بَيْنَ يَدَىْ بَعْضِ الصَّفِّ ثُمَّ نَزَلَ عَنْهُ فَصَفَّ مَعَ النَّاسِ ‏.‏
