"I asked 'Aishah: 'How did the Messenger of Allah ﷺ sleep while he was Junub? Did he perform Ghusl before sleeping or sleep before performing Ghusl?' She said: 'He did both. Sometimes he would perform Ghusl then sleep, and sometimes he would perform Wudu' then sleep.'"  

سَأَلْتُ عَائِشَةَ كَيْفَ كَانَ نَوْمُ رَسُولِ اللَّهِ ﷺ فِي الْجَنَابَةِ أَيَغْتَسِلُ قَبْلَ أَنْ يَنَامَ أَوْ يَنَامُ قَبْلَ أَنْ يَغْتَسِلَ قَالَتْ كُلُّ ذَلِكَ قَدْ كَانَ يَفْعَلُ رُبَّمَا اغْتَسَلَ فَنَامَ وَرُبَّمَا تَوَضَّأَ فَنَامَ  

[Machine] Narrated Yahya ibn Yamar: I asked Aisha, "Did the Messenger of Allah ﷺ sleep while he was in a state of sexual impurity?" She replied, "Perhaps he would perform ablution before sleeping, and perhaps he would sleep before performing ablution. However, he would always perform ablution." She added, "All praise is due to Allah who made ease in religion."  

عَنْ يَحْيَى بْنِ يَعْمَرَ قَالَسَأَلْتُ عَائِشَةَ هَلْ كَانَ رَسُولُ اللهِ ﷺ يَنَامُ وَهُوَ جُنُبٌ؟ قَالَتْ لِي رُبَّمَا اغْتَسَلَ قَبْلَ أَنْ يَنَامَ وَرُبَّمَا نَامَ قَبْلَ أَنْ يَغْتَسِلَ وَلَكِنَّهُ كَانَ يَتَوَضَّأُ قَالَ الْحَمْدُ لِلَّهِ الَّذِي جَعَلَ فِي الدِّينِ سَعَةً
