حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ عُمَرَ، رَضِيَ اللَّهُ عَنْهُ قُلْتُ يَا رَسُولَ اللَّهِ أَيَرْقُدُ أَحَدُنَا وَهُوَ جُنُبٌ قَالَ نَعَمْ إِذَا تَوَضَّأَ.
It was narrated from Ibn 'Umar, from ‘Umar [that he said: ] I said: O Messenger of Allah, can one of us go to sleep when he is junub? He said: “Yes, if he does wudoo'.”
