وَحَدَّثَنِي عَبْدُ الْحَمِيدِ بْنُ بَيَانٍ الْوَاسِطِيُّ، حَدَّثَنَا خَالِدٌ، - يَعْنِي الطَّحَّانَ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَأْمُرُنَا إِذَا أَخَذْنَا مَضْجَعَنَا أَنْ نَقُولَ ‏.‏ بِمِثْلِ حَدِيثِ جَرِيرٍ وَقَالَ ‏"‏ مِنْ شَرِّ كُلِّ دَابَّةٍ أَنْتَ آخِذٌ بِنَاصِيَتِهَا ‏"‏ ‏.‏
