"When the Prophet (ﷺ) bowed he was balanced, he did not make his head higher or lower than his back, and he put his hands on his knees."
Sunan an-Nasa'i Book 12, Hadith 11
← Previous Hadith "Abu Mus'ad said: 'Shall I not show you how the Messenger of Allah (ﷺ) prayed?' We said: 'Yes.' So he stood up and said the takbir, and when he bowed, he held his arms out from his sides until, when every part of him settled, he raised his head. He prayed four rak'ahs like that, and said: 'This is how I saw the Messenger of Allah (ﷺ) praying.'"
