The Noble Qur'an is basically a book of human guidance. Allah the Omnipotent shows us in this practical book how He wants us to live. After all, He, as the Creator of the entire universe including mankind, knows best what is ultimately good, and what is ultimately bad for us. Today's plight of mankind is the very heart of this issue. For a few centuries, mankind had been deceived into believing that it knew better what was good and what was bad for it, and it lived a life of its own with very little regard for the wishes of Allah the Exalted. Then it found out all sorts of miseries such as AIDS, drugs, high rates of crime, divorce, and violence, in a world where economic, racial, and political slavery prevail. An important part of the Great Qur'an forms a comprehensive foundation on which sound systems of social justice, politics, economics, legislation, jurisprudence, world order, global responsibilities towards Nature, and so forth, can be constructed.
