حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ - وَاللَّفْظُ لاِبْنِ الْمُثَنَّى - قَالاَ حَدَّثَنَا مُحَمَّدُ، بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي مَسْلَمَةَ، قَالَ سَمِعْتُ أَبَا نَضْرَةَ، يُحَدِّثُ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ أَخْبَرَنِي مَنْ، هُوَ خَيْرٌ مِنِّي أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لِعَمَّارٍ حِينَ جَعَلَ يَحْفِرُ الْخَنْدَقَ وَجَعَلَ يَمْسَحُ رَأْسَهُ وَيَقُولُ ‏"‏ بُؤْسَ ابْنِ سُمَيَّةَ تَقْتُلُكَ فِئَةٌ بَاغِيةٌ ‏"‏ ‏.‏
