[Machine] "That the Prophet ﷺ had sexual intercourse with some of his wives, then he fell asleep and did not perform ablution until he woke up for Fajr prayer. He then performed ablution, prayed, and completed his fasting."  

الكبرى للنسائي:٣٠٠٣أَخْبَرَنِي مُحَمَّدُ بْنُ إِسْمَاعِيلَ بْنِ إِبْرَاهِيمَ ابْنِ عُلَيَّةَ قَاضِي دِمَشْقَ عَنْ أَبِي عَامِرٍ عَنْ أَفْلَحَ عَنِ الْقَاسِمِ

أَنَّ النَّبِيَّ ﷺ «وَاقَعَ بَعْضُ نِسَائِهِ ثُمَّ نَامَ وَلَمْ يَغْتَسِلْ حَتَّى اسْتَيْقَظَ لِلصُّبْحِ فَاغْتَسَلَ وَصَلَّى ثُمَّ أَتَمَّ صِيَامَهُ»
