صحيح البخاري#1929Sahihحَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ هِشَامِ بْنِ أَبِي عَبْدِ اللَّهِ، حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، عَنْ أَبِي سَلَمَةَ، عَنْ زَيْنَبَ ابْنَةِ أُمِّ سَلَمَةَ، عَنْ أُمِّهَا ـ رضى الله عنهما ـ قَالَتْ بَيْنَمَا أَنَا مَعَ، رَسُولِ اللَّهِ صلى الله عليه وسلم فِي الْخَمِيلَةِ إِذْ حِضْتُ فَانْسَلَلْتُ، فَأَخَذْتُ ثِيَابَ حِيضَتِي فَقَالَ " مَا لَكِ أَنُفِسْتِ ". قُلْتُ نَعَمْ. فَدَخَلْتُ مَعَهُ فِي الْخَمِيلَةِ، وَكَانَتْ هِيَ وَرَسُولُ اللَّهِ صلى الله عليه وسلم يَغْتَسِلاَنِ مِنْ إِنَاءٍ وَاحِدٍ، وَكَانَ يُقَبِّلُهَا وَهُوَ صَائِمٌ.
Narrated Zainab:(daughter of Um Salama) that her mother said, "While I was (lying) with Allah's Messenger (ﷺ) underneath a woolen sheet, I got the menstruation, and then slipped away and put on the clothes (which I used to wear) in menses. He asked, "What is the matter? Did you get your menses?" I replied in the affirmative and then entered underneath that woolen sheet. I and Allah's Messenger (ﷺ) used to take a bath from one water pot and he used to kiss me while he was fasting
Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. When they judged only its chain of narrators (“Isnaad”), the label says “Sound chain”. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
