كُنْتُ أَنَا وَرَسُولُ اللَّهِ، صلى الله عليه وسلم نَبِيتُ فِي الشِّعَارِ الْوَاحِدِ وَأَنَا طَامِثٌ حَائِضٌ فَإِنْ أَصَابَهُ مِنِّي شَىْءٌ غَسَلَ مَكَانَهُ لَمْ يَعْدُهُ ثُمَّ صَلَّى فِيهِ ثُمَّ يَعُودُ فَإِنْ أَصَابَهُ مِنِّي شَىْءٌ فَعَلَ مِثْلَ ذَلِكَ غَسَلَ مَكَانَهُ لَمْ يَعْدُهُ وَصَلَّى فِيهِ .
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."
