وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، نُمَيْرٍ قَالاَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، ح وَحَدَّثَنَا رِفَاعَةُ بْنُ الْهَيْثَمِ، حَدَّثَنَا خَالِدٌ، - يَعْنِي الطَّحَّانَ - كِلاَهُمَا يَقُولُ عَنْ حُصَيْنٍ، عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ، عَنْ جَابِرٍ، قَالَ لَوْ كُنَّا مِائَةَ أَلْفٍ لَكَفَانَا كُنَّا خَمْسَ عَشْرَةَ مِائَةً ‏.‏
