The immortality of the Qur'an`s inviolability has a narrative proof of the book and tradition and rational evidence. The narrations from the Qur'an are verse 9 of Surah Al-Hijr and verse 42 of Surah Fussilat in which God has announced the memorization of the Qur'an and the non-entry of falsehood in it, respectively. The present study examines the meaning of these verses on the inviolability of the Qur'an, focusing on the concept of the word jinn. According to the lexical study of this word, the beliefs of ignorance about it, the analysis of the Prophet's audience's intention to use it and the Qur'anic literature around it, proved that from the point of view of the original audience of the Qur'an, the jinn is not crazy, but someone who has been in contact with jinns. They learn priesthood, poetry and magic. Therefore, the authority that divided the Qur'an into parts, considered it a part of the priesthood and a part of the poem, and called the Prophet a sorcerer because of presenting other miracles besides the Qur'an, slandered him and did not reveal the origin of revelation. God, but the jinn knew. Therefore, the Qur'an removes this accusation from the Prophet in the two verses under discussion and the context before and after it, introduces God as both the source of revelation and its memorizer of the devils, and considers the Qur'an itself to be dear and forbidden. And the entry of the jinn into it has negated. Therefore, the Corresponding signification of the verses on the generality and immortality of the Qur'an's inviolability and the understanding of this meaning were rejected for the original audience, although it is possible that there are other indications in these two noble verses on the inviolability of the immortality.
