It was narrated from Qais bin Tihfah Al-Ghifari that his father said:
"The Messenger of Allahﷺ found me sleeping in the masjid on my stomach. He nudged me with his foot and said: 'Why are you sleeping like this? This is a kind of sleep that Allah dislikes,' or 'that Allah hates.'"

حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، عَنِ الأَوْزَاعِيِّ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ قَيْسِ بْنِ طِخْفَةَ الْغِفَارِيِّ، عَنْ أَبِيهِ، قَالَ أَصَابَنِي رَسُولُ اللَّهِ ـ ﷺ ـ نَائِمًا فِي الْمَسْجِدِ عَلَى بَطْنِي فَرَكَضَنِي بِرِجْلِهِ وَقَالَ " مَا لَكَ وَلِهَذَا النَّوْمِ هَذِهِ نَوْمَةٌ يَكْرَهُهَا اللَّهُ أَوْ يُبْغِضُهَا اللَّهُ " .
