Musnad Ahmad 25617

Translation

✧ The Messenger of Allah ﷺ used to open the prayer with the takbir, and the recitation with 'Al-hamdu lillahi Rabbil 'alamin'. When he bowed, he did not raise his head high, nor lower it too much, but kept it in between. When he raised his head from bowing, he did not prostrate until he stood up straight. When he raised his head from prostration, he did not prostrate again until he sat up straight. He used to recite the tashahhud in every two rak'ahs. He disliked spreading his forearms like a beast of prey, and he used to spread his left foot and sit on it while keeping his right foot upright. He used to forbid sitting on the heels like Satan [i.e., the 'aqib al-shaytan' posture]. He used to conclude the prayer with the taslim.
