It was narrated from Maimunah that:

The Messenger of Allah performed prayer wearing a wool cloak. Part of it was over him and part was over her, and she was menstruating.

حَدَّثَنَا سَهْلُ بْنُ أَبِي سَهْلٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، حَدَّثَنَا الشَّيْبَانِيُّ، عَنْ عَبْدِ اللَّهِ بْنِ شَدَّادٍ، عَنْ مَيْمُونَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ صَلَّى وَعَلَيْهِ مِرْطٌ عَلَيْهِ بَعْضُهُ وَعَلَيْهَا بَعْضُهُ وَهِيَ حَائِضٌ ‏.‏
