ابن ماجة:٦١٥ – حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدِ بْنِ ثَعْلَبَةَ الْحِمَّانِيُّ حَدَّثَنَا عَبْدُ الْحَمِيدِ أَبُو يَحْيَى الْحِمَّانِيُّ حَدَّثَنَا الْحَسَنُ بْنُ عُمَارَةَ عَنِ الْمِنْهَالِ بْنِ عَمْرٍو عَنْ أَبِي عُبَيْدَةَ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَغْتَسِلَنَّ أَحَدُكُمْ بِأَرْضِ فَلاَةٍ وَلاَ فَوْقَ سَطْحٍ لاَ يُوَارِيهِ فَإِنْ لَمْ يَكُنْ يَرَى فَإِنَّهُ يُرَى
