Anas b. Malik reported: The Messenger of Allah fell down from a horse and he was grazed and he led the prayer for us sitting, and the rest of the hadith is the same.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ خَرَّ رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ فَرَسٍ فَجُحِشَ فَصَلَّى لَنَا قَاعِدًا . ثُمَّ ذَكَرَ نَحْوَهُ .
