After several days, I discovered what the subject of the Quran is. People read the Quran, but they don’t grasp the majesty of the Quran. The subject of the Quran is to tell humans why God created them. What is this world about? What are the pre-death period and the post-death period? The greatest issue that has been resolved is the question in the mind of all philosophers and thinkers since thousands of years: if God is all-powerful, why is there evil in the world? If God is all-powerful, then the world should be evil-free. But there is evil everywhere.

The historian Gibbon had said: History of mankind is little more than a register of crimes. History is full of crime, war and violence. This existence of evil has been explained. People say that the greatest proof against God's existence is the presence of evil in this world. The concept of the creation plan explains this question. This phenomenon is not evil, it is actually misuse of freedom. It is not really evil. God has placed humans on earth for the purpose of test. For this test, humans have been given freedom. If there is freedom, there is also a right to misuse this freedom.  What is considered evil is in reality a phenomenon of misuse of freedom. This is how evil can be explained.
