Sunan Ibn Majah — The Book of Purification and its Sunnah — Hadith No: 582
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 .
