Islam gives two answers. First, Muslims believe that every human being – regardless of religion – intrinsically distinguishes right from wrong. For example, everyone understands innately that it is wrong to steal. But repeated exposure to false ideas and our own misdeeds weaken our inner sense of judgment. Plus, as individual human beings, there are many things that we lack the wisdom to understand. Therefore, we cannot risk solely relying upon our own potentially faulty ideas of how to live our lives. Instead, we need to look towards divine guidance to learn how to reform and improve ourselves to reach the level of humanity that God created us for.
