This study aims to analyze i‘rab in Arabic syntax from two main perspectives: classical nahwu theory and modern linguistic approaches, as well as to evaluate the application of i‘rab in the construction of Arabic sentences. I‘rab refers to the inflection of a word’s ending, which indicates its syntactic function in a sentence, playing a crucial role in determining the meaning and structure of the sentence in Arabic. In the context of classical nahwu theory, as found in works such as Al-Kitab by Sibawaih and Al-Mufassal by Al-Zamakhsyari, i‘rab functions as a grammatical marker that helps to understand the relationships between the elements of a sentence, such as the subject, object, and complement. In contrast, modern linguistic approaches view i‘rab as one component in a more complex sentence structure, focusing on overall syntactic and semantic analysis. The research methodology employed is qualitative-descriptive with a content analysis approach, where data is collected from library studies covering primary literature in the fields of classical nahwu and modern linguistics. This study analyzes and compares the application of classical nahwu theory with modern linguistic approaches to i‘rab and its impact on understanding sentence structure in Arabic. The results show that although classical nahwu theory and modern linguistic approaches differ in their application of i‘rab, they complement each other in providing a more comprehensive understanding of Arabic sentence syntax. A proper understanding of i‘rab is essential not only in teaching Arabic but also in translating and interpreting Arabic texts, both in academic and practical contexts. This study is expected to contribute to the development of Arabic language teaching and serve as a reference for Arabic scholars interested in syntactic studies and its applications in Arabic sentence analysis.

The supremacy of knowledge plays a central role in building Islamic civilization, both in classical and modern eras. This study aims to analyze the values of the supremacy of knowledge based on the perspectives of the Qur’an, Hadith, and the thoughts of classical scholars such as Al-Ghazali, Ibn Khaldun, and Al-Farabi. Additionally, this research explores the relevance of knowledge in addressing the challenges of globalization and the dynamics of the digital age. Using a descriptive qualitative research method, primary data consisting of Qur'anic verses, Hadith, and classical scholars' works are combined with secondary data, including books on the history of Islamic civilization, scholarly articles, and contemporary references. The research findings indicate that knowledge is regarded as the main pillar in building a civilization rooted in Islamic values. The Qur’an and Hadith explicitly position knowledge as both an obligation and a path to the glory of individuals and society. The thoughts of classical scholars highlight the importance of integrating religious knowledge and general knowledge to create a balance between worldly and spiritual happiness. In the modern era, the supremacy of knowledge remains relevant as a tool to address the challenges of globalization, particularly through the use of technology and innovation based on Islamic values. This study concludes that the synergy between religious knowledge and modern science can shape a progressive and morally upright Islamic civilization. Knowledge not only serves as a medium for social transformation but also as a spiritual foundation for building a resilient Muslim identity in the contemporary era. The relevance of the values of the supremacy of knowledge provides a strategic guide for Muslims to contribute to global civilization without losing the essence of Islam.
