وَحَدَّثَنِى مُحَمَّدُ بْنُ حَاتِمٍ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنِ ابْنِ جُرَيْجٍ أَخْبَرَنِى أَبُو الزُّبَيْرِ أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ قَالَ اشْتَرَكْنَا مَعَ النَّبِىِّ -صلى الله عليه وسلم- فِى الْحَجِّ وَالْعُمْرَةِ كُلُّ سَبْعَةٍ فِى بَدَنَةٍ فَقَالَ رَجُلٌ لِجَابِرٍ أَيُشْتَرَكُ فِى الْبَدَنَةِ مَا يُشْتَرَكُ فِى الْجَزُورِ قَالَ مَا هِىَ إِلاَّ مِنَ الْبُدْنِ. وَحَضَرَ جَابِرٌ الْحُدَيْبِيَةَ قَالَ نَحَرْنَا يَوْمَئِذٍ سَبْعِينَ بَدَنَةً اشْتَرَكْنَا كُلُّ سَبْعَةٍ فِى بَدَنَةٍ.
