This research deals with a comparative study of two great scholars in their books, namely (Zudbat Al-I'rab) by Al-Qayyoghaqi, and (Solution to the Secrets of the Good People) by Zaini Zadeh. This is in their parsing of the book (Revelation of Secrets in Grammar) by Al-Barkawi, and in this research, we try to shed light on the most important differences in their methodologies. This is due to the importance of the Book of Manifestation; Because his author, namely Al-Barkawi, is a scholar who is proficient in the various Arabic sciences, in addition to his depth in the Sharia sciences as well. He is considered an encyclopedia in terms of classification, authorship, and teaching of the various sciences that we mentioned. He is similar to Al-Suyuti in terms of the diversity of his sciences and works, so it is natural. To find in his writings scientific material, opinions, and interpretations that are his own, or that the scholars who preceded him went along with, and among these issues combined and important for the book Al-Izhar, and the many explanations and comments on it, as well as its parsing by the two scholars, mentioned above, it is necessary for us to begin the research with a prelude to defining the budget in Language and terminology, and then we followed it with two topics: The first topic was titled: Balancing the general approach in the two books, and included the foundations that constitute a prominent phenomenon in both books and included several issues, including: the nature of style, presentation of evidence, interpretation of terms and abandoning them, and control of pronunciation.
