Attitudes are relatively stable assessments of various phenomena in the social world in people's minds. Functional Attitude Theory examines the inner motivations of human beings, the cause of attitudes and their role and function in creating social behaviors. In Haft Owrang poetry, the poet's use of allegory and the narrative format, in most cases, has contributed greatly to the emergence of Jami's views on individual, interpersonal and social issues. The present article has studied the subject of "Hypocritical Sufis" from the perspective of analyzing their personality and behavior based on Functional Attitude Theory using analytical-descriptive method. The result of the research shows that the attitude of different social classes towards the phenomenon of hypocrisy and its manifestation in the Jami’, s age as "Hypocritical Sufis" can be classified into two "profit-seeking" and "value-seeking" functions. Also, the role of political and cultural conditions, traditions and customs of society, as well as the function of mysticism can be considered in this field. Despite the relative stability of Jami's view, the study of the contradiction in attitude as "cognitive inconsistency" is also important in Jami's Haft Owrang, where the poet has implemented the two approaches of "attitude justification" and "following destinism" in this component.
