Menog I xrad is a text entry in Middle Persian language and includes answers that the fictional character "Dana" asks from Menog I xrad. Golestan-E Saadi is a book written by Saadi. The purpose of the present research, which was carried out in a descriptive-analytical way, is to answer the question of what are the primary areas of the concept of metaphor "injustice" in these two texts based on the theory of "contemporary metaphor" and what is the result of comparing them with each other. The findings of this research, considering the way “Injustice” is conceptualized, can somewhat clarify the difference between the concept of ”Injustice” in the human thought in these two books, due to the difference in the philosophical, social, political and moral view of the two periods of Iran (pre-Islamic and Iran of 7th Hijri. 8 name mappings: action, power, fault, object, lesson, material, prison and job for the concept of "injustice" found in two texts. The name mappings of action and power with frequency difference were common in both texts.

“Injustice” as a defect was observed only in the Menog I xrad and “Injustice” as an object, lesson, subject, prison and job only in Golestan-E Saadi. It seems that the functioning of Iran's social life was less complicated in the era when the Menog I xrad was compiled and the government structure was less complicated. In fact, it has presented itself less in the form of government structures such as "prison" and people with governmental position and as "jobs".
