It was narrated that ‘Aishah said:
“The Prophet ﷺ used to spend the night in a state of sexual impurity, then Bilal would come to him and inform him that it is time for prayer. So he would get up and have a bath, and I would see the water dripping from his head, then he would go out and I would hear his voice during Fajr prayer.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ مُطَرِّفٍ، عَنِ الشَّعْبِيِّ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ كَانَ النَّبِيُّ ـ ﷺ ـ يَبِيتُ جُنُبًا فَيَأْتِيهِ بِلاَلٌ فَيُؤْذِنُهُ بِالصَّلاَةِ فَيَقُومُ فَيَغْتَسِلُ فَأَنْظُرُ إِلَى تَحَدُّرِ الْمَاءِ مِنْ رَأْسِهِ ثُمَّ يَخْرُجُ فَأَسْمَعُ صَوْتَهُ فِي صَلاَةِ الْفَجْرِ . قَالَ مُطَرِّفٌ فَقُلْتُ فِي رَمَضَانَ قَالَ رَمَضَانُ وَغَيْرُهُ سَوَاءٌ .
