"Style" in Noldeke's Theory of the Sequence of Revelation

In his sequence of revelation theory, Noldeke uses various tools to discover the sequence of revelation. One of his most utilized and basic tools is "style". The present paper seeks to identify and study Noldeke's use of this tool with a descriptive-analytical method. It explains and evaluates his understanding of the "style" and its application in this theory. The study shows that he considers the "style" as a way of expressing the meaning, purpose, and type of expressions used in the text. He uses "style" to determine the four-phase chronology of his theory, to separate some verses from surah, and to detect how a surah is descended. He also uses it as an instrument to testify other tools for discovering the sequence of revelation. However, his method to use "style" for discovering the sequence of revelation is incomplete and inaccurate, which has prevented Noldeke from achieving true and accurate results.
