حَدَّثَنَا يَعْقُوبُ حَدَّثَنَا أَبِي عَنِ ابْنِ إِسْحَاقَ حَدَّثَنِي نَافِعٌ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ عَنْ أَبِيهِ قَالَ سَأَلْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَيْفَ يَصْنَعُ أَحَدُنَا إِذَا هُوَ أَجْنَبَ ثُمَّ أَرَادَ أَنْ يَنَامَ قَبْلَ أَنْ يَغْتَسِلَ قَالَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِيَتَوَضَّأْ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ لِيَنَمْ
مسند امام احمد بن حنبل · Hadith 94
It was narrated from 'Abdullah bin 'Umar, that his father said: I asked the Messenger of Allah what one of us should do if he becomes junub then wants to sleep before doing ghusl. The Messenger of Allah (PBUH) said: "Let him do wudoo' as for prayer, then he may go to sleep."
