In the Qur'an, along with prayers, commands, prohibitions and high moral standards, God communicates many secrets to mankind. These are truly important secrets, and an attentive eye can witness these throughout his life. No other source than the Qur'an holds these secrets. The Qur'an is the unique source of secrets that those people, no matter how intelligent, literate or astute they are, could never hope to find anywhere else. That some people cannot see while others have a grasp of some hidden messages in the Qur'an is another secret created by God. Those who do not seek these secrets revealed in the Qur'an, live in distress and difficulty. Ironically, they never know the cause of their distress. Those who learn about these secrets of the Qur'an, on the other hand, lead an easy, joyful life. This book deals with the subjects related to some verses God has revealed to mankind as a secret. When a person reads these verses, and his attention is drawn to the secrets in these verses, what he must do is to seek the divine purposes hidden in events and evaluate everything in the light of the Qur'an. Then, people will realise with excitement that the secrets of the Qur'an control both their own lives and those of others alike.
