One of the indications of the loftiness of speech and the sophistication of its words is the accuracy of its language, the goodness of its eloquence and its eloquence, and this is through the coherence of its chosen words and the harmony of their connotations. The consistency of its texts cannot be achieved except by the coherence of the words used, and the first is connected to the last word used in its text or speech. And what creates a rhythm. Text linguistics was able to realize advanced stages that sentence linguistics was unable to reach, as it was able to specify the relationships that connect sentences and text elements at the grammatical, semantic, or lexical level. And text grammar as it is considered one of the best linguistic approaches that dealt with text. ; Because its structure is integrated, it searches for the links that organize the text and achieve its textuality. This is achieved by achieving the process of communication within the text. Because the textual approach views the text as a unified whole in which the parts are interconnected and formulated, Since consistency is proven by a category of tools and means, and one of the most important of these tools is the “indicators”, which I will examine from two aspects: a theoretical aspect in which I clarify the concept of a priori referral (previous) and a posteriori referral (later), as well as clarifying internal referral (textual) and external referral ( Maqamiyya) and their impact on Surat Al-Kahf. As for the other side, the blessed verses will be investigated, which are pronouns, demonstrative nouns, and relative nouns. They require the reader to contemplate their referential structures, and the extent of the availability of their referential elements in Surat Al-Kahf, and in which verse is characterized by cohesion or textual cohesion. ? And stand on the indications in the blessed verses; This is done by applying it to the verses mentioned in the blessed Surah. To what extent do Mushairat contribute and are in harmony with the alayat alkarimuh. . We relied on the descriptive, analytical, and statistical approach, and adopted random selection in selecting the verses. As well as clarifying the most important results reached by the research, the referents had a prominent role in the blessed Surah, and among the various referring tools, pronouns emerged at a rate of (58.25%), relative nouns at a rate of (21.27%), and demonstrative nouns at a rate of (20.48%).
