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).
