"While I was lying down with the Messenger of Allah ﷺ under a blanket, my period came so I slipped away and put on the clothes I used to wear when I was menstruating. The Messenger of Allah ﷺ said: 'Are you menstruating?' I said: 'Yes.' Then he called me to lie down with him under the blanket." This is the wording of 'Ubaidullah bin Sa'eed.[1] [1] That is, one of the narrators in one of the chains, as the author reported it through different chains, as he did when it preceded, see No. 284.  

بَيْنَمَا أَنَا مُضْطَجِعَةٌ مَعَ رَسُولِ اللَّهِ ﷺ إِذْ حِضْتُ فَانْسَلَلْتُ فَأَخَذْتُ ثِيَابَ حَيْضَتِي فَقَالَ رَسُولُ اللَّهِ ﷺ أَنَفِسْتِ قُلْتُ نَعَمْ فَدَعَانِي فَاضْطَجَعْتُ مَعَهُ فِي الْخَمِيلَةِ وَاللَّفْظُ لِعُبَيْدِ اللَّهِ بْنِ سَعِيدٍ
