The study also addressed the types of inimitability Al-Awtabi spoke about in his books, such as rhetorical inimitability and legislative inimitability. The study also aimed to conclude the applications of Al-Awtabi to the kinds of inimitability throughout his books (Al-Ibana Fi Al-Lugha Al-Arabiah) and (Al-Deiaa). The study depended on the historical approach in terms of investigating Al Awtabi's personality and the precedence of his addressing to Quran inimitability in comparison with the opinions of the early scholars who addressed the inimitability. The study also used the inductive approach to study (Al-Ibana Fi Al-Lugha Al-Arabiah) and (Al-Deiaa) books to Induce the subjects in which Al Awtabi referred or explicitly mentioned Quran inimitability. The analytical approach was used to analyze the places that do not contain any reference by Al AwtabI About inimitability. The study concluded some results; the most important of which are as follows: The great scholar Al-Awtabi used a unique style for Quran interpretation, even though his literature did not address Quran interpretation directly. He also addressed various aspects of Quran inimitability. According to Al-Awtabi, the Quran is inimitable in terms of his wonderful style. The great scholar Ibn Barakah also agreed to this concept. According to the research conducted by this researcher, Ibn Barakah and Al-Awtabi were the only two scholars who addressed Quran Inimitability in the first Ibadi literature. The study also revealed that the great scholar Al-Awtabi is distinguished by spotting the light ه on the rhetorical inimitability in the single word by presenting more than one meaning for a single word; which can be found a lot in different spots of his two books. The study also showed that Al-Awtabi was one of the scholars who contributed to establishing the roots of legislative inimitability. The researcher recommended to reconsider and conduct further studies for the literature of Al-Awtabi to discover a more accurate history of the era in which he lived. The researcher also recommended shedding light on other aspects of his personality.
