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  

[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  

[Machine] I asked Aisha, "How did the Messenger of Allah ﷺ act when he wanted to sleep while in a state of sexual impurity?" She said, "He would perform ablution as he does for prayer, then he would sleep."  

سَأَلْتُ عَائِشَةَ كَيْفَ كَانَ رَسُولُ اللَّهِ ﷺ يَصْنَعُ إِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ؟ فَقَالَتْ كَانَ «يَتَوَضَّأُ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ يَنَامُ»  

"عَنْ عمر قالَ: سألتُ رسولَ اللَّه ﷺ كَيْفَ يصنعُ أحدُنَا إِذَا هُوَ أجْنَبَ، ثم أرادَ أن ينامَ قبل أن يَغْتَسِل؟ فَقَالَ: لِيتَوَضَّأ وضوءَهُ للصَّلَاةِ، ثمَّ لِيَنَمْ".
