This book has been written to make the reader realize the danger of religions of irreligion and the responsibility he bears. Enjoining good and forbidding evil is an important aspect of worship commanded by Allah of believers, who are protectors of one another, and the book is a reminder of this noble responsibility. Anyone who reads or hears the reminder has one of two choices: sitting back and saying, "Someone else will do it anyway," or shouldering the responsibility Allah has bestowed upon him and starting to work immediately.
In their struggle against disbelief the prophets and true believers set a good example. All of the prophets whose stories are related in the Qur’an and the true believers who followed them fought against disbelief and strove throughout history to eliminate irreligious ideologies and convey to people the oneness of Allah. They used many different methods to spread this message to people, and nothing stopped them. Their ambition, commitment, patience and courage should be an example to all believers.
Prophet Muhammad (saas) stated that there will be a reward for inviting people to righteousness:
In recent history there have been numerous scholars of Islam whose lives were exemplary in this sense. For instance, Bediüzzaman Said Nursi was a noble person who all through his life struggled against the religions of irreligion under very trying circumstances. He displayed an unyielding patience and made many sacrifices in an effort to protect his country and people from this threat. The following statements of Bediüzzaman inspire great zeal to those of conscience and sound mind:
A conscientious person is duty bound to follow the voice of his conscience and immediately seek ways to serve Allah's religion. Allah will distinguish His servants who have true faith from those who merely say "I have faith" yet avoid the struggle that faith demands. Allah states in the Qur’an:
Do people think that they will be left to say, 'We believe,' and they will not be tried? 125
In another verse Allah states that believers cannot attain true faith and Paradise unless they struggle against irreligion:
Or do you think that you will enter Paradise while Allah has not made evident those among you who struggle and made evident those who are steadfast?126
