[Machine] That the Prophet ﷺ had intimate relations with some of his wives, then slept until morning, and then he performed a ritual bath while he was in a state of impurity.  

الكبرى للنسائي:٣٠٠١أَخْبَرَنَا الْحَسَنُ بْنُ مُحَمَّدٍ الزَّعْفَرَانِيُّ عَنْ حَمَّادِ بْنِ خَالِدٍ عَنْ أَفْلَحَ بْنِ حُمَيْدٍ عَنِ الْقَاسِمِ عَنْ عَائِشَةَ

أَنَّ النَّبِيَّ ﷺ «أَصَابَ بَعْضَ نِسَائِهِ ثُمَّ نَامَ حَتَّى أَصْبَحَ وَاغْتَسَلَ وَهُوَ جُنُبٌ»
