In the course of our journey through this book we shall study the revelations of the Quran a journey that will take us from the bottom of the sea to the heights ofspace from the creation of the universe to the latest discovery on the firmamentfrom the embryo to the life of bees and from the most probing questions of philosophy to the most complicated problems of physics. In this expedition we shall try to assess the unbelievers' contention that "The Quran is the word of a human" as opposed to "The Quran is the word of God." We shall witness that the Quran is exempt from all errors despite the vast range of subjects it covers and that it reveals information that was not - and could not possibly be - known at the time.
