حَدَّثَنَا أَحْمَدُ بْنُ إِشْكَابَ، قَالَ: حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ لَيْثٍ، عَنْ مُحَمَّدِ بْنِ عَمْرِو بْنِ عَطَاءٍ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: مَنْ نَامَ وَبِيَدِهِ غَمَرٌ قَبْلَ أَنْ يَغْسِلَهُ، فَأَصَابَهُ شَيْءٌ، فَلا يَلُومَنَّ إِلا نَفْسَهُ.
