Intertextuality is of the recent issues in the field of literary studies, dealing with the relationship between two texts. Different theorists have clarified this method with different approaches and analyzes. Genette is one of the most famous contemporary theorists in the field who has studied in detail the types of intertextual relations and how they are analyzed. Among the religious texts, the relationship between Nahj al and the Holy Qur’ an, especially considering that Imam Ali (Pbuh) is considered as the spoken Qur’ an and has been emphasized on his accompaniment with the Qur’ an, has always been the subject of Nahj ’ s commentators. Applying the method of intertextuality in analyzing this relationship not only helps to deepen our understanding of both the Quran and, but leads to have in hand a standard method to study it. This method has several functions, one of which is the correction of texts. Regarding this purpose, the present paper investigates and concludes that this method could recognize the (unintentionally change), darj (insertion), and (cluttering) in ’ s text. is sometimes done in vocabulary signs, and sometimes in the root of the words, of which ten examples were found in. Another damage was the insertion of one or more words in the text of a, of which two examples were found there. The other is cluttering of the text of a of which only one was found there.
