Musnad Ahmad 30:2652

Waki' narrated to us, Hammad narrated to us, from Muhammad ibn Ziyad, from Abu Hurairah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Leave me as I have left you, for those who were before you were only destroyed by their excessive questioning and their disagreement with their prophets. So if I command you to do a matter, then follow it as much as you are able, and if I forbid you from a thing, then avoid it."
