Semantics, as a science and with a historical approach, examines the semantic changes of words related to a language over time, to make it easier to understand poetic or prose texts of that language. Semantics, which is a branch of the science of semantics and was proposed by Ferdinand de Saussure in the 19th century, is responsible for this. This research work, using a descriptive-analytical method, has investigated the temporal semantics of the semantic field of the words injustice and justice in the Holy Qur'an and Jahili poetry, and by analyzing these words in Jahili poetry and then in the Qur'an, it has investigated their semantic relationships and has come to the conclusion that Firstly, there is a connection between the words of Jahili poems and the Qur'an, and secondly, the main and famous meanings of the words in the semantic field of injustice and justice and their derivatives were formed before the Islamic period, and some of them underwent semantic changes during the same period, which in addition to the main concepts They have also indicated new meanings. The emergence of Islam and the flow of Quranic verses on languages had a great impact on the evolution of Arabic words, especially words in the semantic field of injustice and justice, so that the coexistence of these words with Quranic words and placing them in a new context, the process of their semantic development became more impressive. . Also, the words of the semantic domain of injustice and justice have been able to be used as a substitute for these two words due to the very close semantic connection with these two words. The importance of this research in the analysis of the historical course is a part of the semantic fields of two widely used words, and the author was able to give a practical form to his learning and take a step, albeit a small one, in order to reduce the difficulties of research work in the field of linguistics. In the future, students' research works will enter this field
