If you read the Quran, you will find that it deals with all of the subjects relating to human beings. But the basic theme of the Quran is the creation plan of God. All other subjects touched on by the Quran are related to this basic theme, directly or indirectly. God Almighty created the universe, and it is God Almighty who revealed this book called Quran. The primary purpose of the Quran is to reveal that divine plan according to which the world was created and people were settled in it. This theme, which is central to the Quran, is thus described in chapter 67 Al-Mulk (The Kingdom): “He created death and life so that He might test you, and find out which of you is best in conduct”. (67: 2) The word ‘life’ represents pre-death period and the word ‘death’ represents the second period, which may be called the post-death period. The pre-death period is very short, about a hundred years, while the post-death period has no such limit. It will continue for all eternity.
