1. Although the Arabic word Iman is traditionally translated as belief, the word holds a special significance in the Qur'an. In Qur'anic terms, Iman is the committed conviction in the existence and attributes of the Creator and Sustainer of the universe and the transcendental truths according to His revealed scriptures, including His attributes, powers and authority. Iman requires reasonable knowledge of this matter. So the principle for Iman is to be committed in the truth of the scriptures revealed to the chosen messengers of God based on the signs of those matters in which there is ultimate knowledge, and to believe in all the information contained in such books, and not to make any information subject to faith without the evidence of such scriptures.
2. The word Iman in terms means 'belief in the information presented by revelation by the Prophets or according to the revealed law of God'. However, the word is also used in a literal sense at some places. For example, believing in something unreasonable or without the basis of acceptable reasoning is called 'Iman bil batil' (irrational belief).
3. Although the word Iman means faith, it does not mean only the general belief or acceptance of the existence or oneness of God, but firm belief without any doubt, in view of which a commitment to act according to the demands of faith is created, that is called Iman. Therefore, violating God's commands and prohibitions without any special justification is considered as evidence of not having faith in that matter.
4. There is no opportunity to force people about faith, in this case everyone has the opportunity to believe or disbelieve of their own free will. In some cases, even after believing, there is a possibility of returning to disbelief. That is, freedom has been given to people regarding Iman. However, if he exercises this freedom and believes and does good deeds according to the demands of faith, he will be rewarded in this world and the hereafter, and if he does not believe, he will be harmed in this world and the hereafter. Disbelief is a religious behavioral crime, for which he will be punished in the Hereafter, but due to freedom in this matter on earth, no man or authority can punish another man for religious reasons.
5. God does not make anyone responsible beyond his capacity. He does not do the slightest injustice to anyone. Therefore, in the judgment of faith and good deeds, everyone will be rewarded or punished with due justice. In making a person responsible for believing and doing good deeds, his actual condition and cognitive and operational capabilities or environmental opportunities and capabilities will be considered.
6. One of the main matters of Iman is to believe in all the prophets and messengers sent by God and all the books or scriptures revealed by him. The last Prophet Muhammad rasulullah and the last book Qur'an. Qur'an is the authenticating book of its predecessors and the eternal law for mankind. Therefore the ahle-kitab or the followers of the previous books are also called to believe in the Qur'an. However, they should be called upon in this matter on the basis of the same content as 'what is between them and the mumin or believers'.
7. A mu'min must be a Muslim or a submitter to God and a Muslim or a submitter to God must also strive to hold Iman or firm belief. The religious formal identity of believers is called 'Muslim'. It is the duty of every believer to be God-conscious as much as possible and to continue to desire and strive to die as a Muslim.
8. According to the Qur'an, the subject of Iman is: faith in God, His angels, His prophets, His books, and the Hereafter. Belief in God must be free from polytheism. Shirk is associating anyone with the existence, attributes, powers and rights of God. One of the practical aspects of shirk is 'accepting any other law in addition to the Book of God as the main code of life'. In other words, accepting anything other than the revealed scriptures of God as proof of religion is shirk.
