This research deals with the text relations in the Quranic chapter Mu'minun such as lexical relations (appropriateness, omission, and repetition) with an emphasis on primary and secondary meanings. Then the study connects all these relations and makes use of phonemic implications and meanings of the letters in the Quranic verses, particularly the Quranic intervals, and their internal and emotional implications especially in text relations (repetition). Meanwhile, it does not ignore communicative and instrumental functions of language. This is more evident at the Qur'an intervals and in phonemes ending in "alif", "ya", and "waw" according to which these functions take different meanings. For example, the phonemes ending in "fa", "ha", "aa", "wa" in the words "fa'ilun", "hafizun", "warithun", "khaalidun" refer to the continuity, duration, and the time and place comprehensiveness of those attributes and actions. In addition, the phonemes ending in "ya" indicate humbleness and the phonemes ending in "waw" implicate institutionalization and internality. These findings, based on a descriptive- analytical method, are an attempt to show the eternal Qur'anic miracles.
