There are many people who have no faith in the Qur'an despite claiming to be faithful believers. They spend their lives clinging to delusions and live with contradictions and deficiencies, refusing to adopt the Qur'an as their guide. Yet, only the Qur'an provides a lifetime of true knowledge for every person and contains the secrets of God's creation in its truest and purest form. Any piece of information not based on the Qur'an is in contradiction, and therefore is a deception and an illusion. Therefore, those who do not adhere to the Qur'an live in a state of delusion. In the hereafter they will be condemned to eternal punishment (unless God wills otherwise).

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. (from the introduction)
