Surah Al-Jinn, as one of the important surahs of the Holy Quran, presents a clear horizon for understanding the process of Quranic guidance by expressing the reaction of the jinn to the revelation and explaining the position of servitude and mission. This research, with a descriptive-analytical approach and using three theoretical frameworks including Halliday and Hassan's theory of textual coherence, Sperber and Wilson's theory of relevance, and Allameh Tabataba'i's purpose-centered approach, has analyzed the thematic coherence and semantic structure of Surah Al-Jinn. Analysis of the structure of the surah shows that the verses are arranged in two main contexts: the first context (verses 1 to 19), which refers to the reaction of the jinn to the Quran, the importance of pure servitude, and perseverance in the path of Roushd, and the second context (verses 20 to 28), which is dedicated to completing the argument with the polytheists, explaining the position of the Prophet and revelation, and determining the correct path of Roushd. The findings indicate that intertextual coherence in the surah is established through mechanisms such as reference, semantic contrast, causal explanation, and conceptual reflection, and through this, a coherent framework is formed for understanding the guiding purpose of the surah. This semantic and thematic coherence allows concepts such as the correct path of life and immunity from deviation to be recognized in the framework of understanding "Roushd" as the guiding purpose of the surah.
