The Messenger of Allah ﷺ said, "Do not race ahead of me in bowing or prostration, for whatever I get ahead of you with when I bow, you will catch up with me when I rise. I have grown heavy in body."
حدثنا مسدد حدثنا يحيى عن ابن عجلان حدثني محمد بن يحيى بن حبان عن ابن محيريز
قال رسول الله ﷺ لا تبادروني بركوع ولا بسجود فإنه مهما أسبقكم به إذا ركعت تدركوني به إذا رفعت إني قد بدنت
[Sahih] Ibn Majah narrated it in the Book of Establishing Prayers, Chapter on the Prohibition of Preceding the Imam in Ruku and Sujud, no. 963, from the hadith of Yahya Qattan, with this wording. Ibn Khuzayma graded it sahih, no. 1594, as did Ibn Hibban (Al-Ihsan), nos. 2226 and 2227. Its chain of transmission is hasan, and the hadith has corroborating narrations.
