Research on the role of different nations in Islamic sciences is of special importance, especially for that nation itself. Throughout the history of Islam, Iranians have provided many scientific services to various Islamic sciences such as Hadith, Tafsir, Arabic literature, etc. This article with the descriptive-analytical method and by collecting information by library method, seeks to answer the question of what role Iranians played in the science of recitation (Qira’, t) and its ups and downs during the First nine centuries (from the beginning of Islam to the revival of the science of recitation (Qira’, t) by Ibn Jazari, a century and a half after the Mongol attack)? The history of recitation (Qira’, t) in Iran before Islam, the first Iranian teachers of Quranic recitations (Qira’, at), the geographical distribution and canvases of Iranian recitation (Qira’, t) masters, the presence of Iranians among the seven reciters, the reactions of Iranian scholars to the choice of the seven reciters by Ibn Mujahid and the foundation of the authority of recitations (Qira’, at), are some of the issues that are discussed in this the article has been reviewed. Finally, it can be concluded that although Iranian reciters did not have a special role in the early stages of the formation of recitations (Qira’, at), in the later stages, including in terms of existence among the seven reciters, and the rejection or development of the theory of seven reciters, they flourished and their active and fruitful presence can’, t be ignored. Also, the intellectual spirit of some Iranians prevented them from sticking to the recitation (Qira’, t) of a single reciter, thus they started to select and “, choice”,among the recitations. Finally, after the Mongol invasion, recitation (Qira’, t) circles in Iran faced a severe decline, and about a century and a half later, efforts to revive it began again.
