Every book has its objective and the objective of the Quran is to make man aware of the Creation plan of God. That is, to tell man why God created this world; what the purpose is of settling man on earth; what is required from man in his pre-death life span, and what he is going to confront after death. Man is born as an eternal creature. When God created man as such, He divided his life span into two periods, the pre-death period, which is a time of trial, and the post-death period, which is the time for receiving the rewards or punishment merited by one's actions during one's lifetime. These take the form of eternal paradise or eternal hell. The purpose of the Quran is to make man aware of this reality. This is the theme of this divine Book, which serves to guide man through his entire journey through life into the after-life.

It would be correct to say that man is a seeker by birth. These questions lurk in everyone's mind: Who am I? What is the purpose of my life? What is the reality of life and death? What is the secret of man's success and failure? etc. According to the Quran, the answer to these questions is that the present world is the testing ground and whatever man has been endowed with in his pre-death period is all a part of the test. The Hereafter is the place where the result of the test will be taken into account by the Almighty and whatever man receives in the life after death, by way of reward or punishment, will be commensurate with his deeds in this world. The secret of man's success in this life is to understand God's creation plan and map out his life accordingly.
