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.’”

حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، أَنْبَأَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللَّهِ، قَالَ ذُكِرَ لِرَسُولِ اللَّهِ ﷺ رَجُلٌ نَامَ لَيْلَةً حَتَّى أَصْبَحَ قَالَ " ذَلِكَ الشَّيْطَانُ بَالَ فِي أُذُنَيْهِ " .
