باب تَرْكِ الْوُضُوءِ مِنْ مَسِّ الرَّجُلِ امْرَأَتَهُ مِنْ غَيْرِ شَهْوَةٍ
Sunan an-Nasa'i 166
It was narrated that 'Aishah said:
"The Messenger of Allah (ﷺ) used to pray when I was lying in front of him as the bier is placed (in front of the Imam), and when he wanted to pray Witr he would nudge me with his foot."
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ عَبْدِ الْحَكَمِ، عَنْ شُعَيْبٍ، عَنِ اللَّيْثِ، قَالَ أَنْبَأَنَا ابْنُ الْهَادِ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ، قَالَتْ إِنْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَيُصَلِّي وَإِنِّي لَمُعْتَرِضَةٌ بَيْنَ يَدَيْهِ اعْتِرَاضَ الْجَنَازَةِ حَتَّى إِذَا أَرَادَ أَنْ يُوتِرَ مَسَّنِي بِرِجْلِهِ ‏.‏
