If one sleeps and does not offer the night prayer
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا أَبُو الأَحْوَصِ، قَالَ حَدَّثَنَا مَنْصُورٌ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ ذُكِرَ عِنْدَ النَّبِيِّ صلى الله عليه وسلم رَجُلٌ فَقِيلَ مَا زَالَ نَائِمًا حَتَّى أَصْبَحَ مَا قَامَ إِلَى الصَّلاَةِ. فَقَالَ " بَالَ الشَّيْطَانُ فِي أُذُنِهِ ".
Narrated `Abdullah: A person was mentioned before the Prophet (p.b.u.h) and he was told that he had kept on sleeping till morning and had not got up for the prayer. The Prophet (ﷺ) said, "Satan urinated in his ears."
