Hadith 4662

(حديث مرفوع) حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ ، عَنْ عُبَيْدِ اللَّهِ ، أَخْبَرَنِي نَافِعٌ ، عَنِ ابْنِ عُمَرَ ، أَنَّ عُمَرَ سَأَلَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : أَيَنَامُ أَحَدُنَا وَهُوَ جُنُبٌ ؟ قَال : نَعَمْ ، إِذَا تَوَضَّأَ " .
It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that Sayyiduna Umar (may Allah be pleased with him) asked the Noble Prophet (peace and blessings be upon him): If a person becomes impure by choice, can he sleep in that state? The Noble Prophet (peace and blessings be upon him) said: "Yes, he should perform ablution and then sleep."
