The Prophet ﷺ used to pray while I used to sleep beside him during my periods (menses) and in prostration his garment used to touch me.
سَمِعْتُ مَيْمُونَةَ تَقُولُ كَانَ النَّبِيُّ ﷺ يُصَلِّي وَأَنَا إِلَى جَنْبِهِ نَائِمَةٌ فَإِذَا سَجَدَ أَصَابَنِي ثَوْبُهُ وَأَنَا حَائِضٌ وَزَادَ مُسَدَّدٌ عَنْ خَالِدٍ قَالَ حَدَّثَنَا سُلَيْمَانُ الشَّيْبَانِيُّ وَأَنَا حَائِضٌ
[Machine] I heard Maymuna, the wife of the Prophet ﷺ, say: "The Messenger of Allah ﷺ used to stand up and pray at night, and I would be sleeping beside him. When he prostrated, his clothes would touch me, and I was menstruating."
سَمِعْتُ مَيْمُونَةَ زَوْجَ النَّبِيِّ ﷺ تَقُولُ كَانَ رَسُولُ اللهِ ﷺيَقُومُ فَيُصَلِّي مِنَ اللَّيْلِ وَأَنَا نَائِمَةٌ إِلَى جَنْبِهِ فَإِذَا سَجَدَ أَصَابَنِي ثِيَابُهُ وَأَنَا حَائِضٌ
