One of the characteristics of the Holy Quran and the fundamental beliefs of Muslims is the incorruptibility of the divine word. This topic has been the focus of commentators and Quran scholars from the past until now. This article, in a descriptive-analytical way and with a Qur'anic and narrative approach, specifies that Imam Fakhrazi under the following verse: "Inna nanahu nazlana dhikr wa inna laho lahafizoon" declares his opinion on the non-distortion of the Qur'an and believes that according to this verse there is no There is no increase or decrease in the Holy Quran. Because if something was added or subtracted from it, the order of the Qur'an would be disturbed, and wise men understood this issue. Allameh Tabatabai clearly stated his opinion under the following verses: "This is the Book of Al-Aziz* La Yaatiyeh Al-Bateel Min Bayin Yadiya and La Min Khalfeh" and they believe that the Holy Qur'an is immune from any increase, decrease, or deficiency. And referring to hadiths distorts them, which are against the book and should be rejected. And the meaning of opposing these narrations with the Quran is not only opposing the appearance of the mentioned two verses, because the appearance of the words of the verse is a speculative evidence and for this reason it is against the definitive meaning of the Holy Quran.
