سنن أبي داود

Salim reported on the authority of his father (Ibn ‘Umar): 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."
