Hadith 474
Chapter 62: Ablution after a sleep - كتاب الطهارة وسننها
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا الأَعْمَشُ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَنَامُ حَتَّى يَنْفُخَ ثُمَّ يَقُومُ فَيُصَلِّي وَلاَ يَتَوَضَّأُ . قَالَ الطَّنَافِسِيُّ قَالَ وَكِيعٌ تَعْنِي وَهُوَ سَاجِدٌ .
It was narrated that `A'ishah said:
"The Messenger of Allah would fall asleep until he was breathing deeply, then he would get up and offer the prayer, and he did not perform ablution." (Hasan) Tanafisi said: "Waki` said: 'She meant while he was prostrating (he would sleep).'"
