حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَنْبَأَنَا مَعْمَرٌ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ عُمَرَ رَضِيَ اللَّهُ عَنْهُ سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِثْلَهُ
مسند امام احمد بن حنبل · Hadith 236
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."
