I said to myself, I shall watch how the Messenger of Allah ﷺ prays. So I watched him.He stood and said the takbir, raising his hands until they were level with his ears. Then he placed his right hand over his left palm, wrist, and forearm. When he wanted to bow, he raised his hands in the same manner.He placed his hands on his knees, then when he raised his head, he raised his hands in the same way again. Then he prostrated, placing his palms level with his ears.Then he sat, spreading out his left leg beneath him, placing his left palm on his left thigh and knee, and resting the edge of his right elbow on his right thigh. He folded two of his fingers and made a ring, then raised his index finger, and I saw him moving it, supplicating with it.
أخبرنا سويد بن نصر قال أنبأنا عبد الله بن المبارك عن زائدة قال حدثنا عاصم بن كليب قال حدثني أبي أن
قلت لأنظرن إلى صلاة رسول الله ﷺ كيف يصلي فنظرت إليه فقام فكبر ورفع يديه حتى حاذتا بأذنيه ثم وضع يده اليمنى على كفه اليسرى والرسغ والساعد فلما أراد أن يركع رفع يديه مثلها قال ووضع يديه على ركبتيه ثم لما رفع رأسه رفع يديه مثلها ثم سجد فجعل كفيه بحذاء أذنيه ثم قعد وافترش رجله اليسرى ووضع كفه اليسرى على فخذه وركبته اليسرى وجعل حد مرفقه الأيمن على فخذه اليمنى ثم قبض اثنتين من أصابعه وحلق حلقة ثم رفع إصبعه فرأيته يحركها يدعو بها
