Hadith 2105
Abu Huraira (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "Leave me as I leave you regarding matters; for those before you were destroyed only because of their excessive questioning and their disagreement with their prophets. So when I forbid you from something, avoid it, and when I command you to do something, do it to the best of your ability."
