Mukhtasar Muslim

Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him), he states that he heard the Messenger of Allah (peace and blessings be upon him) saying: "Whatever I forbid you from, abstain from it, and whatever I command you to do, do it to the best of your ability. Indeed, those before you were only destroyed because of their excessive questioning and their disagreement with their prophets."
