Narrated `Abdullah:
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 " .
It was mentioned before the Prophet (ﷺ) that there was a man who slept the night till morning (after sunrise). The Prophet (ﷺ) said, "He is a man in whose ears (or ear) Satan had urinated."
