Someone said to him, "Tell us about the prayer of the Messenger of Allah ﷺ."So he stood before us in the mosque and pronounced the takbir. When he bowed, he placed his hands on his knees with his fingers pointing downward, and he held his elbows away from his sides until every part of him settled.Then he said, "Allah hears the one who praises Him," and rose until every part of him settled.Then he pronounced the takbir and prostrated, placing his palms on the ground and holding his elbows away from his sides until every part of him settled.Then he raised his head and sat until every part of him settled, and he did the same again.Then he prayed four units of prayer like this unit, completing his prayer. Then he said, "This is how we saw the Messenger of Allah ﷺ pray."
حدثنا زهير بن حرب حدثنا جرير عن عطاء بن السائب عن سالم البراد قال أتينا عقبة بن عمرو الأنصاري
له حدثنا عن صلاة رسول الله ﷺ فقام بين أيدينا في المسجد فكبر فلما ركع وضع يديه على ركبتيه وجعل أصابعه أسفل من ذلك وجافى بين مرفقيه حتى استقر كل شيء منه ثم قال سمع الله لمن حمده فقام حتى استقر كل شيء منه ثم كبر وسجد ووضع كفيه على الأرض ثم جافى بين مرفقيه حتى استقر كل شيء منه ثم رفع رأسه فجلس حتى استقر كل شيء منه ففعل مثل ذلك أيضا ثم صلى أربع ركعات مثل هذه الركعة فصلى صلاته ثم قال هكذا رأينا رسول الله ﷺ يصلي
[Its isnad is hasan] Nasai narrated it in "Al-Tatbiq," chapter on the positions of the hands in ruku, no. 1037, from the hadith of Ata bin Saaib, and he narrated it before his confusion set in. Ibn Khuzayma graded it sahih, no. 598, as did Hakim, 1/234, and Dhahabi agreed with him.
