حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ ذُكِرَ عِنْدَ النَّبِيِّ صلى الله عليه وسلم رَجُلٌ نَامَ لَيْلَهُ حَتَّى أَصْبَحَ، قَالَ "ذَاكَ رَجُلٌ بَالَ الشَّيْطَانُ فِي أُذُنَيْهِ ـ أَوْ قَالَ ـ فِي أُذُنِهِ "
