Recognition the relationship of the verses inside a Surah and structural research of that Surah are new approaches that although there were detailed in earlier commentaries, but has been considered so seriously by more recent Qur’ān scholars. According to the science of Surah recognition, every Surah has a purpose and its own specific main subject, so that the all verses of Surah circulate around it thereby the meaningful relationship between its verses are recognised. In this study, according to the method of Surah recognition, the conceptive structure of the two Surahs Nās and ʿAṣr and the links and reciprocal interaction between the two Surahs Nās and Falaq as a case study are reviewed. Therefore, this research revolves around two axes: Methodology of structural research in the Qur’ān; including topics like: Stages and principles of structural research, thematic units (Rukūʿāt) and gradual revelation of the Qur’ān, linkage and connection between the Surahs, thematic axis or basic subject of Surahs, difference between structural research and interpretation, and at the end of this paper, the meaning and structural cognition of the two Surahs Nās and ʿAṣr are discussed. Based on this research, the exact semantic connection between Surah Nās and Falaq was extracted, and then Surah ʿAṣr was conceptualized using the method of pondering (tadabbur); and as a result, it was concluded that Surah ʿAṣr, despite its small volume, is the most comprehensive and complete Surah of the Qur’an, which contains heavenly and life-giving Quranic teachings.

Among the miraculous aspects of the Holy Quran, the rhetorical subtleties in the verses of this divine book have long been the focus of scholars and scholars of Quranic sciences. One of the rhetorical topics of the Holy Quran is stylistics, which by taking advantage of the achievements of the science of rhetoric,we investigate the stylistic effects in the Holy Quran. Surah "Ghashiyeh" as one of the clear examples of a systematic language is full of verbal signs, where the harmonious words that create the internal beat of the verses and the intervals of the verses lead to the external music of the verses. In this research, based on linguistic analysis at three phonetic, lexical, and grammatical levels, we discuss the stylistics of Surah Ghashieh. The present research tries to show that it is the linguistic features in the verses of the Holy Quran that cause the change of style in the verses at different levels. Applying repetition techniques,Sajja,Puns, respect for example, and contrast emphasize rhetorical elegance in addition to melodiousness. In fact, these stylistic features make this blessed Surah suitable and melodious.

Stylistic studies look at the literary text as a homogeneous and coherent unit that we cannot isolate its parts from each other. In this study, Surah Yunus has been studied in terms of its Phonetics aspect, which is one of the most important issues in stylistic studies. This study aims at revealing the relationship between sound and meaning in this Surah and the extent of the cohesion and harmony between these sounds and their implications. This study was based on the statistical method in the distribution and analysis of the voices in the Surah. In this research, it was discovered that, in the Quran, the voices have been amazingly used. So, you can guess the meaning by the type of voices which is used in the verses. And it was found that this Surah has unity in terms of rhythm, and tends to present loud sounds. It was also repeated with a large number of clear voices such as soft and accent voices. This is common in the Arabic speech. In fact, the Surah has followed in this field of Arabic language structure. This rhythm in the Surah presents almost smooth and flexible rhythm, which is rarely seen its tones goes up or down except when necessary. The voices came in harmony with the content and purpose of the verses, so that their voices cannot be replaced by others, and the verse remains as it is a sign of significance and beauty.

Stylistics as a modern method explores Linguistic and Stylistic Phenomena since form or content by itself is not sufficient to attain the gist of the text. In Stylistics, the quality of the connection of the two and their effect on leading to understand are worked on. Finally, modes of aesthetics and the most important Stylistic characteristics are considered.Quran’s explanations wonderfully fascinate humans thought and emotion and its beauty is manifested in Quran’s eloquent discourse and its profound discourse. Al-Rahman Surah is one of the most beautiful Surahs of Quran which describes a lot of God’s blessings. The present study is going to explore Al-Rahman Surah stylistically using descriptive-analytic method in four levels of phonetic, syntactic, lexical, and semantic.This study is going to answer some questions as what is the most obvious stylistic characteristic of Al-Rahman Surah, and what is the effect of word selection on communicating meaning. Rhyming and abundance of Leen and Mad letters are of the most obvious characteristics of Al-Rahman Surah that have strong effect on the rhyme of Surah. In addition, repetition is another phenomenon which adds to the effect & emphasis on the meaning. Also, in this study in order to attain the eloquence purposes of the writer, we consider the quality of distributing Esmie and Felie sentences and past, present, passive and active verbs.
