(13) Chapter: The fasting is valid for the one who is Junub when dawn comes
باب صِحَّةِ صَوْمِ مَنْ طَلَعَ عَلَيْهِ الْفَجْرُ وَهُوَ جُنُبٌ
‘A’isha, the wife of the Messenger of Allah (ﷺ), said:
The dawn broke upon the Messenger of Allah (ﷺ) during the Ramadan in a state of junub not because of sexual dream (but on account of intercourse) and he washed himself and observed fast.
