It is difficult to determine the official administrative history of Astan Quds Razavi. In different historical periods from the Ghaznavids to the present, there has always been a person in charge of managing the affairs of the holy shrine of Imam Reza (AS), who was initially called the Naqib and later the Safavids the Mutawali. This article examines, from the aspect of documentary and documentary research, a sign and a charter issued by the Naqba of the Holy Shrine in the Timurid period. The most important questions of this article are: What are the most important documentary components in the documents under study? What is their informational and content value, and what is the structural difference between the documents issued by the Holy Shrine and the charter issued by Sultan Hussein Bayaqa? The research findings show that the custodians of the Holy Shrine were considered among the scholars and men of honor of this period, and their religious and political status, along with the religious dignity of the shrine of Imam Reza (AS), provided the elements of power that enabled the issuance of a seal and charter to manage the affairs of this religious institution. In addition, the issuance of these documents is evidence that the Timurid kings, in addition to respecting the shrine and sending exquisite gifts and offerings, also granted it an independent administrative identity. A comparative study of the documents also shows that the documentary components of the documents of the Holy Shrine largely correspond to the government charter, and there is only a difference in the tone and content of the issuance of the document.
