The new Sassanian administrative divisions, the substitute for the former administrative system and the country, were divided into four sections. The purpose of the research is to study written sources of literature, including the writings of early Islamic historians and geographers, as far as possible, a general picture of the position of the Nanina administrative system as a subset of his administrative system can be drawn. So, the questions here are raised 1. What is the history of human presence in the cultural landscape of Nain? 2. Regarding the administrative divisions of the Nain region during the Sassanid period and, as a matter of fact, the revelation of the coming of Islam was considered one of the ancient kilns? The adopted method is a combination of historical methods and the historical geographic area. The results of the research showed that the oldest evidence of human presence in the region dates back to prehistoric times and we do not know about the fate of the region before the Sassanid era, and archaeological excavations and studies can explain the status of this region. With the advent of Islam, especially the early Islamic centuries, Nain was considered one of the largest furnaces of the Fars capital.
