Bukhari :: Book 9 :: Volume 92 :: Hadith 391
Narrated Abu Huraira:
The Prophet said, "Leave me as I leave you) for the people who were before you were ruined because of their questions and their differences over their prophets. So, if I forbid you to do something, then keep away from it. And if I order you to do something, then do of it as much as you can."
