The sexually impure person sleeping as he is without touching water
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ إِنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ إِنْ كَانَتْ لَهُ إِلَى أَهْلِهِ حَاجَةٌ قَضَاهَا ثُمَّ يَنَامُ كَهَيْئَتِهِ لاَ يَمَسُّ مَاءً .
It was narrated that 'Aishah said: "The Messenger of Allah, if he needed any of his wives, would satisfy his needs then he would sleep as he was, without touching water."
