حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ شُعْبَةَ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ بُشَيْرِ بْنِ يَسَارٍ، عَنْ سُوَيْدِ بْنِ النُّعْمَانِ ـ وَكَانَ مِنْ أَصْحَابِ الشَّجَرَةِ ـ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَصْحَابُهُ أُتُوا بِسَوِيقٍ فَلاَكُوهُ. تَابَعَهُ مُعَاذٌ عَنْ شُعْبَةَ.
