حَدَّثَنَا عَبْدُ الرَّزَّاقِ حَدَّثَنِي مَعْمَرٌ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِثْلَهُ أَنَّ عُمَرَ سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
مسند امام احمد بن حنبل · Hadith 4930
It was narrated from Ibn 'Umar that 'Umar asked the Prophet (PBUH) can one of us go to sleep when he is junub? He said: "Yes, but let him do wudoo' as for prayer." Naafi' said: If Ibn 'Umar wanted to do that, he would do wudoo' as for prayer,except his feet.
