Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Prophet (peace and blessings of Allah be upon him) said: "As long as I leave you alone, you should also leave me alone (and do not ask unnecessary questions), because the nations before you were destroyed due to their (unnecessary) questions and their disagreements with their prophets. So when I forbid you from something, then avoid it, and when I command you to do something, then do it to the best of your ability."
