ABSTRACT
Since the beginning of the transfer of knowledge from the mind to the lines of books in the history of Islam, many valuable books have been written on many subjects, including matters of faith. These sources have shed light on the path of the Islamic Ummah in every period and have helped Muslims maintain their faith within the framework of the Qur'an and Sunnah. Through the writing of such works through the ages, a number of useful and multifaceted goals have also been achieved. One of these goals has helped groups and peoples who accept Islam to abandon their old unfounded beliefs that cling to their consciences. In this way, they have a perfect faith, believing in the unity of Allah. These sources also seek to correct false beliefs that differ from one period to another and are distorted and altered by impostors, thus leading to Muslims breaking away from Islam. I should emphasize here that my work, which is currently in the hands of readers, aims for the same goals. It should be noted that in recent times some suspicious groups have tried to confuse minds and confuse targets by suggesting misleading philosophical, esoteric and ideological ideas. Warning believers, calling them to resist these gangs and fight their destructive activities, is undoubtedly the duty of those who have taken on the protection of knowledge and morality. This book is written on the basis of the integrity and perfection of the Qur'an. It also confirms that if a person believes in the indivisible integrity of the Qur'an, he is a believer. But if a person's faith is contrary to the values in the Qur'an and Sunnah, such a person cannot have any relationship with Islam. This book has another important purpose; This goal also proves that it is not possible for a person to gather two contradictory beliefs in his conscience at the same time. One cannot accept two different religions together. As for those who commute between contradictory beliefs and worship according to more than one religion, they are not essentially unaware of what they have committed, but rather have some goals that they want to achieve in their interests.
