'A'isha reported: The Messenger of Allah ﷺ used to begin prayer with takbir (saying Allahu Akbar) and the recitation: "Praise be to Allah, the Lord of the Universe". When he bowed he neither kept his head up nor bent it down, but kept it between these extremes; when he raised his head after bowing he did not prostrate himself till he had stood erect; when he raised his head after prostration he did not prostrate himself again till he sat up. At the end of every two rak'ahs he recited the Tahiyya; and he used to place his left foot flat (on the ground) and raise up the right; he prohibited the devil's way of sitting on the heels, and he forbade people to spread out their arms like a wild beast. And he used to finish the prayer with the taslim.
This hadith teaches us about how important it is to perform our prayers in a proper manner as prescribed by Prophet Muhammad so that we can reap its full benefits spiritually as well as physically. It also teaches us about being mindful while praying; focusing on our prayers instead of letting our minds wander off elsewhere or getting distracted by other things around us. Moreover, this hadith also emphasizes on following certain etiquettes during prayer such as not spreading out arms like a wild beast which shows respect for God's house i-e mosque or any other place where we are offering our prayers at that time.
