God has placed man in this world for a greater purpose: to settle him in a perfect world where he will live forever. To guide humanity on what must be done to achieve this, God initiated the succession of prophets. God sent His prophets to the world to make mankind aware of this Creation Plan and to teach them how to live in accordance with the creation plan of God.  The existence of man is such a unique phenomenon that no other such example can be found throughout the vastness of the cosmos. Man is rightly called the ‘best of all creations,’ which means the best and most meaningful ‘being’ among all the things created. Such a meaningful existence cannot be without purpose. God has created man as an eternal creature and has divided his life into two stages—the pre-death period, the limited life in this world, and the post-death period, or the eternal life after death. According to the creation plan of God, every person must spend a period of trial in this present, imperfect world, and after this, according to his deeds, he will earn the right to inhabit the perfect and eternal world called Paradise or live in eternal deprivation. The present temporary world is for a test for which everyone has been given freedom. If one discovers God and lives a God-oriented life in this world, God may find him eligible for living in Paradise in the world Hereafter. This is the scheme of existence for this world devised by its Creator. The fundamental aim of creation is to select those who are fit to inhabit the world of Paradise.
