عَنْ أُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يُجْنِبُ ثُمَّ يَنَامُ ثُمَّ يَنْتَبِهُ ثُمَّ يَنَامُ
It is narrated from Sayyida Umm Salama (may Allah be pleased with her), she says that when the Messenger of Allah (peace and blessings be upon him) would become in a state of janabah, he would sleep, then wake up, and then sleep again.
