حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَنْبَأَنَا عُبَيْدُ اللَّهِ بْنُ عُمَرَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ عُمَرَ رَضِيَ اللَّهُ عَنْهُ سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ هَلْ يَنَامُ أَحَدُنَا وَهُوَ جُنُبٌ قَالَ نَعَمْ وَيَتَوَضَّأُ وُضُوءَهُ لِلصَّلَاةِ
مسند امام احمد بن حنبل · Hadith 235
It was narrated from Ibn 'Umar that 'Umar (RA) asked the Prophet (PBUH): Can one of us sleep if he is junub ? He said: "Yes, if he does wudoo' as for prayer."
