[Machine] That the Messenger of Allah ﷺ used to go out for Fajr prayer with his head dripping wet, then he would fast.  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ «يَخْرُجُ إِلَى صَلَاةِ الصُّبْحِ وَرَأْسُهُ يَقْطُرُ ثُمَّ يَصُومُ»  

[Machine] The Messenger of Allah ﷺ used to go out for prayer with drops falling from his head while he was in a state of sexual impurity. So, he would perform ritual ablution (ghusl) while intending to fast.  

لَقَدْ كَانَ رَسُولُ اللهِ ﷺ «يَخْرُجُ إِلَى الصَّلَاةِ وَرَأْسُهُ يَقْطُرُ كَانَ جُنُبًا فَاغْتَسَلَ وَهُوَ يُرِيدُ الصَّوْمَ»
