حَدَّثَنَا الرَّبِيعُ بْنُ نَافِعٍ، حَدَّثَنَا مُعَاوِيَةُ، - يَعْنِي ابْنَ سَلاَّمٍ - عَنْ زَيْدٍ، أَنَّهُ سَمِعَ أَبَا سَلاَّمٍ، قَالَ حَدَّثَنِي السَّلُولِيُّ، - هُوَ أَبُو كَبْشَةَ - عَنْ سَهْلِ ابْنِ الْحَنْظَلِيَّةِ، قَالَ ثُوِّبَ بِالصَّلاَةِ - يَعْنِي صَلاَةَ الصُّبْحِ - فَجَعَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي وَهُوَ يَلْتَفِتُ إِلَى الشِّعْبِ . قَالَ أَبُو دَاوُدَ وَكَانَ أَرْسَلَ فَارِسًا إِلَى الشِّعْبِ مِنَ اللَّيْلِ يَحْرُسُ .
