Narrated Anas (RA):

Allah's Messenger (ﷺ) prayed and an orphan and I prayed behind him and Umm Sulaim (RA) was behind us. [Agreed upon and the wording is al-Bukhari's].

وَعَنْ أَنَسٍ قَالَ: { صَلَّى رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-فَقُمْتُ وَيَتِيمٌ خَلْفَهُ, وَأُمُّ سُلَيْمٍ خَلْفَنَا.‏ } مُتَّفَقٌ عَلَيْهِ, وَاللَّفْظُ لِلْبُخَارِيّ ِ [1]‏ .‏
