(11) باب نَوْمِ الرَّجُلِ مَعَ حَلِيلَتِهِ فِي الشِّعَارِ الْوَاحِدِ وَهِيَ حَائِضٌ
It was narrated that 'Aishah said:
"The Messenger of Allah (ﷺ) and I would sleep under a single blanket when I was menstruating. If anything got on him from me, he would wash that spot and no more, and pray in it, then come back. If anything got on it again from me, he would do likewise and no more, and he would pray in it."
