Sunan Abi Dawud Book 2, Hadith 331
I saw the Messenger of Allah(ﷺ) that when he began prayer, he used to raise his hands opposite his shoulders, and he did so when he bowed, and raised his head after bowing. Sufyan(a narrator) once said: “When he raised his head:; and after he used to say: “When he raised his head after bowing. He would not raise (his hands) between the two prostrations."
A youth from the Quraish passed in front of Abu Sa’id al-Khudri who was praying. He repulsed him. He returned again. He then repulsed him for the third time. When he finished the prayer, he said: Nothing cuts off prayer; but the Messenger of Allah (ﷺ) said: Repulse as much as you can, for he is just a devil.
Abu Dawud said: If two traditions of the prophet(ﷺ) conflict, the practice of the Companions after him should be taken into consideration.
The Messenger of Allah (ﷺ) used to raise his hands opposite his shoulders when he began prayer, then he uttered takbir (Allah is most great) in the same condition, and then he bowed. And when he raised his back (head) after bowing he raised them opposite his shoulders, and said: “Allah listens to him who praises Him.” But he did not raise his hand when he prostrated himself; he rather raised them when he uttered the takbir (Allah is most great) before bowing until his prayer is finished.
