Sunan an-Nasa'i 385
أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، عَنْ سُفْيَانَ، عَنْ مَنْبُوذٍ، عَنْ أُمِّهِ، أَنَّ مَيْمُونَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَضَعُ رَأْسَهُ فِي حِجْرِ إِحْدَانَا فَيَتْلُو الْقُرْآنَ وَهِيَ حَائِضٌ وَتَقُومُ إِحْدَانَا بِخُمْرَتِهِ إِلَى الْمَسْجِدِ فَتَبْسُطُهَا وَهِيَ حَائِضٌ .
Muhammad ibn Mansur informed us, from Sufyan, from Manbuth, from his mother, that Maymunah said: The Messenger of Allah (ﷺ) would rest his head in the lap of one of us and recite the Qur'an while she was menstruating. One of us would carry his khumrah to the mosque and spread it out while she was menstruating.
Translation notes
The full chain through Manbuth and his mother is included although the witness begins with Maymunah. Khumrah is retained as the mat carried to the mosque.

The English witness omits the Arabic chain.
Please verify the chain against the Arabic source.
