"Pretending" is a social harm that, although it is also felt in communications between ordinary people in society, recognizing pretense and correctly confronting a pretender who is in government positions is much more complex and difficult due to the various sources of power. In this article, pretense is considered as a "cultural-communicational harm" and the goal is to explain the pattern of Imam Reza's confrontation with Ma'mun as a pretender who is in the highest ranks of the government. To achieve this pattern, the method of text hermeneutics with an "interrogative and author-centered" approach and content analysis were used to collect data from the narrations and life of Imam Reza and to analyze the data. By examining the lexical meaning of the word "tolerance" and carefully examining the narrations in this field and applying it to the life of Imam Reza, as well as analyzing the content of Imam Reza's verbal and non-verbal actions, 44 basic themes, 6 organizing themes, and one comprehensive theme were obtained. “Foresightful tolerance”, “measurement in actions”, “exposing pretense while tolerating the pretense”, “benevolence and observing expediency”, “observing Islamic principles”, and “strict confrontation in case of ineffective tolerance” are 6 organizing themes that are placed under “wise tolerance” as a comprehensive theme. “wise tolerance” should be considered as a communication principle in confronting pretense. The wise attribute of the spirit is the governing tolerance in confronting the pretense. In fact, tolerance is done with the pretense person, not with his pretense. It is suggested that the model of confronting pretense agents in the current situation be the subject of another article and that by updating the model obtained from this article, the current model of confronting pretense can be drawn.
