The mysterious letters, the philosophy of existence and the meaning of these letters in the Qur'an is one of the mysterious issues that has always occupied the minds of Interpreters. Each Interpreter has tried to provide his own interpretation and understanding of these mysterious letters. Since these letters are part of the surah of the Qur'an and at the same time, the appearance of these letters, unlike other verses, does not indicate meaning, the commentators have approached these verses with their preconceptions. In this article, an attempt has been made to investigate the role of pre-interpreters of descriptors in a descriptive and analytical method in finding the meaning of syllables. However, each of them has tried to interpret the letters with their own preconceptions and interpret the desired meaning based on it. Alam al-Huda, due to his rationalism and unparalleled mastery of Arabic theology and literature, has tried to provide a rational interpretation of the syllables in accordance with the custom and circumstances of the time of the revelation. On the other hand, Sadra and Gonabadi consider travel and cultivation necessary to find the meaning of the Qur'an.
