The Messenger of Allah ﷺ came to us in our house, so I and an orphan boy of ours prayed behind him, and Umm Sulaym prayed behind us.
أخبرنا عبد الله بن محمد بن عبد الرحمن قال حدثنا سفيان قال حدثني إسحق بن عبد الله قال سمعت
أتانا رسول الله ﷺ في بيتنا فصليت أنا ويتيم لنا خلفه وصلت أم سليم خلفنا
Bukhari transmitted it in the Book of Adhan, chapter, "A woman alone forms a row by herself," hadith 727, from the hadith of Sufyan bin Uyayna, with this same wording. It is also found in Kubra, hadith 941.Bukhari's teacher, Abdullah bin Muhammad, is al-Musnadi, not Zuhri, the teacher of Nasai, so this should be noted carefully.
