ذِكْرُ مَا يُسْتَحَبُّ لِلْمَرْءِ إِذَا كَانَ جُنُبًا وَأَرَادَ النَّوْمَ أَنْ يَتَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ يَنَامَ
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. (Using translation from Nasāʾī 256)
«كَانَ رَسُولُ اللَّهِ ﷺ إِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ لَمْ يَنَمْ حَتَّى يَتَوَضَّأَ وَإِذَا أَرَادَ أَنْ يَأْكُلَ * غَسَلَ يَدَيْهِ وَأَكَلَ»
