Sunan Ibn Mājah 1330✓ 5Sahih
حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، أَنْبَأَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللَّهِ، قَالَ ذُكِرَ لِرَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ رَجُلٌ نَامَ لَيْلَةً حَتَّى أَصْبَحَ قَالَ " ذَلِكَ الشَّيْطَانُ بَالَ فِي أُذُنَيْهِ " .
It was narrated that 'Abdullah said:"Mention was made to the Messenger of Allah (ﷺ) of a man who slept until morning came. He said: 'That is because Satan urinated in his ears.'"
