The Holy Quran is outstandingly unique in its miraculous artistic features and distinctive styles that are easily noticed in all of its chapters and verses. Rhetorical transition is seen as one of the most important rhetorical devices and arts frequently used in the Quranic style. In order to comprehend this figure of rhetoric, the writer introduces Chapter "the Cave" -No.18- as a sample. The thesis is thus aimed at investigating the excellent transitional styles in the Book of God. The thesis thus lays much emphasis on the correlation between transition as a rhetorical device and some other rhetorical devices intermingling therewith -such as digression- or opposing it, such as brevity. The significance of the thesis lies in its focus on the persuasively evocative connection between the topics of the Quran and the transition between its verses and chapters, taking into considerable account the contextual perspective and pinpointing the purpose of shifting and the objective of the address. The writer thus concludes that the Holy Quran has kept to the most wonderful style of rhetorical transition in its texts by shifting smoothly from one idea into another and from one story into other several stories all of which bear the same idea with which a Quranic chapter begins. Hence, while moving from one story to another, the Quranic chapter uses an outstandingly wonderful style of rhetorical transition and creates an easily noticed link between the law-related and creed-related facts understood from these stories, thus allowing many features of the Creator’s all-greatness and wonderful making to appear to the recipient effortlessly.
