حَدَّثَنَا الرَّبِيعُ بْنُ نَافِعٍ أَبُو تَوْبَةَ، حَدَّثَنَا شَرِيكٌ، عَنْ أَبِي إِسْحَاقَ، قَالَ وَصَفَ لَنَا الْبَرَاءُ بْنُ عَازِبٍفَوَضَعَ يَدَيْهِ وَاعْتَمَدَ عَلَى رُكْبَتَيْهِ وَرَفَعَ عَجِيزَتَهُ وَقَالَ هَكَذَا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَسْجُدُ ‏.‏
Translation
Narrated Al-Bara' ibn Azib

Al-Bara' ibn 'Azib described to us how the Messenger of Allah (ﷺ) used to prostrate: he placed his hands on the ground, leaned on his knees, and raised his rear, saying, "This is how the Messenger of Allah (ﷺ) used to prostrate."
