[Machine] Bilal used to come to the Prophet ﷺ and inform him of the Fajr prayer, while being in a state of impurity (after sexual intercourse). He would then perform ghusl (ritual bath) and come to the mosque to pray two units of prayer, with his head dripping with impurity, and then observe fasting for that day.
كَانَ بِلَالٌ يَأْتِي النَّبِيَّ ﷺ فَيُؤْذِنُهُ لِصَلَاةِ الْغَدَاةِ وَهُوَ جُنُبٌ «فَيَغْتَسِلُ ثُمَّ يَأْتِي الْمَسْجِدَ فَيُصَلِّي الرَّكْعَتَيْنِ وَرَأْسُهُ يَقْطُرُ مِنَ الْجَنَابَةِ ثُمَّ يَصُومُ ذَلِكَ الْيَوْمَ»
