Narrated Um Salama:
حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ ، قَالَ حَدَّثَنَا هِشَامٌ ، عَنْ يَحْيَى ، عَنْ أَبِي سَلَمَةَ ، عَنْ زَيْنَبَ ابْنَةِ أَبِي سَلَمَةَ ، عَنْ أُمِّ سَلَمَةَ ، قَالَتْ بَيْنَا أَنَا مَعَ النَّبِيِّ، صلى الله عليه وسلم مُضْطَجِعَةً فِي خَمِيلَةٍ حِضْتُ، فَانْسَلَلْتُ فَأَخَذْتُ ثِيَابَ حِيضَتِي فَقَالَ " أَنُفِسْتِ ". فَقُلْتُ نَعَمْ. فَدَعَانِي فَاضْطَجَعْتُ مَعَهُ فِي الْخَمِيلَةِ.
While I was lying with the Prophet (ﷺ) under a woolen sheet, I got my menses. I slipped away and put on the clothes for menses. The Prophet (ﷺ) said, "Have you got your menses?" I replied, "Yes." He called me and I slept with him under the woolen sheet.
