Chapter 164 The Junub Person Washing Only His Hands When He Wants To Eat
باب اقْتِصَارِ الْجُنُبِ عَلَى غَسْلِ يَدَيْهِ إِذَا أَرَادَ أَنْ يَأْكُلَ
It was narrated from 'Aishah that if the Messenger of Allah (ﷺ) wanted to sleep while he was Junub, he would perform Wudu', and if he wanted to eat he would wash his hands.
أَخْبَرَنَا مُحَمَّدُ بْنُ عُبَيْدِ بْنِ مُحَمَّدٍ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، رضى الله عنها أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ تَوَضَّأَ وَإِذَا أَرَادَ أَنْ يَأْكُلَ غَسَلَ يَدَيْهِ .
