حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ مُوسَى الْمَرْوَزِيُّ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، أَخْبَرَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، قَالَ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا سَجَدَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ قَرِيبًا مِنَ السَّوَاءِ . قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ .
