The propaganda of the religion is a process of communication between people and the clergy with the aim of promoting religious teachings; and various types of communication disorders will be an effective obstacle in this regard. Identifying them from the sociological perspective of communication can provide an appropriate version to improve the quality of religious preaching. The conceptual framework of this research is based on the “ meaning source” model, which deals with the communication process and its disorders. Having employed the method of Sandelowski qualitative description and conducted deep interview with the elite Islamic preachers, the researchers described the disorders in Islamic preaching. The field of research was all the clerics whose clerical effort was evaluated in the Islamic Propagation Office every year. The sample selection included 21 elite preachers who had honored in two conferences of “ Preaching Excellence” . Based on the representation of the data, the abandoned concepts of verses and narrations, the subjective interpretation and misreading were categorized as “ Avoiding the Koran” as well as the concepts of dreamer preachers, superstition generation, dervishism and miraculous dignity creation categorized as “ dreaming and superstition” . The participants also described the concepts of content, general and temporal stereotypes under the category of “ preaching stereotypes” ; and the concepts of society-avoidance, function-avoidance, and system-avoidance under the category of “ individual religion. ” .
