أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الْعَزِيزِ بْنِ غَزْوَانَ، قَالَ حَدَّثَنَا الْفَضْلُ بْنُ مُوسَى، عَنْ حُسَيْنٍ، - يَعْنِي ابْنَ وَاقِدٍ - عَنْ عِلْبَاءَ بْنِ أَحْمَرَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي سَفَرٍ فَحَضَرَ النَّحْرُ فَاشْتَرَكْنَا فِي الْبَعِيرِ عَنْ عَشْرَةٍ وَالْبَقَرَةِ عَنْ سَبْعَةٍ .
