حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، ح وَحَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، كِلاَهُمَا عَنِ الأَعْمَشِ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُمَا قَالاَ " مَا أَنْتُمْ يَوْمَئِذٍ فِي النَّاسِ إِلاَّ كَالشَّعْرَةِ الْبَيْضَاءِ فِي الثَّوْرِ الأَسْوَدِ أَوْ كَالشَّعْرَةِ السَّوْدَاءِ فِي الثَّوْرِ الأَبْيَضِ " . وَلَمْ يَذْكُرَا " أَوْ كَالرَّقْمَةِ فِي ذِرَاعِ الْحِمَارِ " .
