أَخْبَرَنَا مُحَمَّدُ بْنُ عَلِيِّ بْنِ حَرْبٍ، قَالَ حَدَّثَنَا مُحْرِزُ بْنُ الْوَضَّاحِ، عَنْ إِسْمَاعِيلَ، - يَعْنِي ابْنَ أُمَيَّةَ - عَنْ أَبِي غَطَفَانَ بْنِ طَرِيفٍ، حَدَّثَهُ أَنَّهُ، سَمِعَ ابْنَ عَبَّاسٍ، يَقُولُ لَمَّا دَفَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم شَنَقَ نَاقَتَهُ حَتَّى أَنَّ رَأْسَهَا لَيَمَسُّ وَاسِطَةَ رَحْلِهِ وَهُوَ يَقُولُ لِلنَّاسِ " السَّكِينَةَ السَّكِينَةَ " . عَشِيَّةَ عَرَفَةَ .
