In the first part of introduction in the literatures of the history of Islamic Iran, Tahmidiehs (praising Allah statements) can be seen that are similar in shape and structure, meanwhile there are some differences are in their contents. These differences are made by various factors. This paper aims to consider the reasons why differences are there in contents, descriptions and interpretations used in Tahmidiehs presented in the literature of the history of Islamic Iran. To explain these differences, some factors, namely religious policies of governors, common religious beliefs and their impacts on the writing methods of Tahmidieh are considered.  The results of this study show that Tahmidiehs are under the effect of the theoretical foundations of governments, cultural-social status, and generally discursive space related to the time they are written.
