Abstract

This article discusses Nahwu's Usul which covers Qiyas, Illat, and Ta'wil using the Library Study method with a Descriptive Historical Qualitative approach. As for the main sources in writing this article are the books that contain the discussion of Qiyas, Illat, and Tawil and their relation to Greek Philosophy. The author concludes that Nahwu Science was born due to errors in reading the Koran because of the occurrence of birth among speakers of Arabic, not because of the influence of Greek Philosophy, but it cannot be denied that certain themes are influenced by other Sciences, such as methods the formation of Arabic rules inspired by the Science of Jurisprudence, and Ta'lil inspired by the way of thinking of the Greek Philosophers, but in general the application of the Nahwu Science had existed before the interaction between Muslim Scientists and Philosophers.
