Musannaf Ibn Abi Shaybah 7339 — Those who said: follow the imam

It is narrated from Muhammad bin Yahya bin Habban that the Messenger of Allah (peace and blessings be upon him) said: "Because of my advanced age my body has become heavy. Do not go ahead of me in bowing and prostration. I may go ahead of you while going into bowing, but you will catch up with me while rising from bowing. I will go ahead of you while going into prostration, but you will catch up with me while rising from prostration."
