Salim reported on the authority of his father (Ibn 'Umar): I saw the Messenger of Allahﷺ 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".
The importance of following this sunnah can be seen in its emphasis on performing each step with utmost care and attention to detail, as even small changes can have a great impact on one’s spiritual journey towards Allah Almighty. Furthermore, it serves as an example for us to follow in order to gain closeness to Allah Almighty through prayerful submission and obedience towards Him alone.
