Al-Adab Al-Mufrad, Book 48, Hadith 1188 (English) ⓘ

Abu Umama reported that the Messenger of Allah, may Allah bless him and grant him peace, passed by a man in the mosque who was lying on his front. He kicked him with his foot and said, "Get up. It is the sleep of Jahannam."

حَدَّثَنَا مَحْمُودٌ، قَالَ‏:‏ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، قَالَ‏:‏ أَخْبَرَنَا الْوَلِيدُ بْنُ جَمِيلٍ الْكِنْدِيُّ، مِنْ أَهْلِ فِلَسْطِينَ، عَنِ الْقَاسِمِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي أُمَامَةَ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم مَرَّ بِرَجُلٍ فِي الْمَسْجِدِ مُنْبَطِحًا لِوَجْهِهِ، فَضَرَبَهُ بِرِجْلِهِ وَقَالَ‏:‏ قُمْ، نَوْمَةٌ جَهَنَّمِيَّةٌ‏.‏
