Sunan Ibn Majah 1704

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، قَالَ سَأَلْتُ أُمَّ سَلَمَةَ عَنِ الرَّجُلِ، يُصْبِحُ، وَهُوَ جُنُبٌ، يُرِيدُ الصَّوْمَ؟ قَالَتْ: كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يُصْبِحُ جُنُبًا مِنَ الْوِقَاعِ، لاَ مِنِ احْتِلاَمٍ، ثُمَّ يَغْتَسِلُ وَيُتِمُّ صَوْمَهُ ‏.‏

It was narrated that Nafi’ said:“I asked Umm Salamah about a man who gets up in the morning when he is in a state of sexual impurity and wants to fast. She said: “The Messenger of Allah (ﷺ) used to get up in the morning in a state of sexual impurity after having intercourse, not from a wet dream, then he would take a bath and complete his fast.’”
