Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, the wife of the Prophet ﷺ used to say, "If you have intercourse with your wife and then wish to go to sleep before doing ghusl, do not sleep until you have done wudu as for prayer."  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا كَانَتْ تَقُولُ إِذَا أَصَابَ أَحَدُكُمُ الْمَرْأَةَ ثُمَّ أَرَادَ أَنْ يَنَامَ قَبْلَ أَنْ يَغْتَسِلَ فَلاَ يَنَمْ حَتَّى يَتَوَضَّأَ وُضُوءَهُ لِلصَّلاَةِ  

I asked the Messenger of Allah ﷺ : O Messenger of Allah ﷺ, if one of us wants to sleep before doing ghusl when he is junub, what should he do? He said: ʿLet him do wudoo’ as for prayer, then sleep.”  

سَأَلْتُ رَسُولَ اللهِ ﷺ قُلْتُ يَا رَسُولَ اللهِ أَحَدُنَا إِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ كَيْفَ يَصْنَعُ قَبْلَ أَنْ يَغْتَسِلَ؟ قَالَ يَتَوَضَّأُ وُضُوءَهُ لِلصَّلاةِ ثُمَّ يَنَامُ  

I asked the Messenger of Allah ﷺ what one of us should do if he becomes junub then wants to sleep before doing ghusl. The Messenger of Allah ﷺ said: “Let him do wudoo' as for prayer, then he may go to sleep.ʿ  

سَأَلْتُ رَسُولَ اللهِ ﷺ كَيْفَ يَصْنَعُ أَحَدُنَا إِذَا هُوَ أَجْنَبَ ثُمَّ أَرَادَ أَنْ يَنَامَ قَبْلَ أَنْ يَغْتَسِلَ؟ قَالَ فَقَالَ رَسُولُ اللهِ ﷺ لِيَتَوَضَّأْ وُضُوءَهُ لِلصَّلاةِ ثُمَّ لِيَنَمْ  

[Machine] Aisha, the wife of the Prophet ﷺ , narrated that she asked him, "What did the Messenger of Allah do when he was in a state of major ritual impurity (junub) and wanted to sleep before performing ablution?" She said, "He would perform ablution for prayer and then go to sleep."  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ قَالَ سَأَلْتُهَا كَيْفَ كَانَ رَسُولُ اللهِ يَصْنَعُ إِذَا هُوَ جُنُبٌ وَأَرَادَ أَنْ يَنَامَ قَبْلَ أَنْ يَغْتَسِلَ؟ قَالَتْ كَانَ يَتَوَضَّأُ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ يَنَامُ
