nasai-kubra:2997Hārūn b. ʿAbdullāh

[Machine] I heard Aisha saying that the Prophet ﷺ used to wake up in a state of janaabah (major ritual impurity) and then he would perform ghusl (ritual bath) and observe fasting for that day.  

الكبرى للنسائي:٢٩٩٧أَخْبَرَنِي هَارُونُ بْنُ عَبْدِ اللهِ قَالَ حَدَّثَنَا أَبُو بَكْرٍ الْحَنَفِيُّ قَالَ حَدَّثَنَا خُثَيْمُ بْنُ عِرَاكِ بْنِ مَالِكٍ قَالَ حَدَّثَنِي سُلَيْمَانُ بْنُ يَسَارٍ قَالَ

سَمِعْتُ عَائِشَةَ تَقُولُ كَانَ النَّبِيُّ ﷺ «يُصْبِحُ جُنُبًا فَيَغْتَسِلُ وَيَصُومُ يَوْمَهُ ذَلِكَ»
