Narrated by:'Aishah said
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."
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 .
