Sunan an-Nasai
أَخْبَرَنَا الْحَارِثُ بْنُ مِسْكِينٍ، قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ وَهْبٍ، عَنْ يُونُسَ، وَاللَّيْثِ، عَنِ ابْنِ شِهَابٍ، عَنْ حَبِيبٍ، مَوْلَى عُرْوَةَ عَنْ بُدَيَّةَ، - وَكَانَ اللَّيْثُ يَقُولُ نَدَبَةَ - مَوْلاَةُ مَيْمُونَةَ عَنْ مَيْمُونَةَ قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُبَاشِرُ الْمَرْأَةَ مِنْ نِسَائِهِ وَهِيَ حَائِضٌ إِذَا كَانَ عَلَيْهَا إِزَارٌ يَبْلُغُ أَنْصَافَ الْفَخِذَيْنِ وَالرُّكْبَتَيْنِ . فِي حَدِيثِ اللَّيْثِ مُحْتَجِزَةً بِهِ .
It was narrated that Maimunah said: "The Messenger of Allah (ﷺ) would fondle one of his wives while she was menstruating, if she wore an Izar (waist wrap) that reached halfway down to the middle of her thighs or to her knees." In the narration of Al-Laith: "Being covered with it."
