Abu Humayd reported,

"I was the most attentive among you in memorizing the prayer of the Messenger of Allah ﷺ. I saw that when he said the opening takbir, he raised his hands level with his shoulders. When he bowed, he placed his hands firmly on his knees, then he straightened his back. When he raised his head from bowing, he stood upright until every vertebra returned to its place. When he prostrated, he placed his hands on the ground neither spread out flat nor clenched, and he pointed the tips of his toes toward the qiblah. When he sat after the first two rak'ahs, he sat on his left foot with the right foot upright. When he sat in the final rak'ah, he placed his left foot forward, kept the right one upright, and sat on his buttocks."

Sahih

عن أبي حميد الساعدي قال

أنا كنت احفظكم لصلاة رسول الله ﷺ، رأيته إذا كبر جعل يديه حذاء منكبيه، وإذا ركع أمكن يديه من ركبتيه، ثم هصر ظهره، فإذا رفع رأسه استوى حتى يعود كل فقار مكانه، فإذا سجد وضع يديه غير مفترش ولا قابضهما، واستقبل بأطراف أصابع رجليه القبلة، فإذا جلس في الركعتين جلس على رجله اليسرى، ونصب اليمنى، وإذا جلس في الركعة الآخرة قدم رجله اليسرى ونصب الأخرى، وقعد على مقعدته.
