One of the new theories in respect of communication and appropriateness between the surah is the plan of communication between the surah of the same group of the Quran. The grouping of surah means that some surah of the Holy Quran have a logical, orderly and related course in terms of content as well as form; in such a way that perhaps the goals of the surah of the same group can be considered as common in general. The basis of grouping the surah of the Holy Quran is a common beginning. In the present study, a new dimension of the structural miracle and order of the Holy Quran has been dealt with and the promotion of proving the order of the Quran has been suggested from the focus of the verse to the focus of the surah. In this way, due to the limited volume, the surah of the same group of Musabbahat, parts 27 and 28 of the Holy Quran (beginning with the glorification of God) have been examined. The results of this research, which have been obtained by using a descriptive-analytical method, show that the surah of Musabbahat in the selected components have common or close content and semantic relations or general relations and examples are coherent subject matter, verbal connections such as the use of common words, etc., which strengthen the group theory of the surah of the Holy Quran. Such researches, in order to introduce new dimensions of the structural miracle of the Quran, provide new perspectives on the subject of Surahology for thinkers, each of which may need more in-depth and accurate studies.
