The necessity of a profound and multidimensional reinterpretation of the concept of hijab in contemporary societies—particularly in the face of modern intellectual and social challenges—constitutes one of the essential needs of Islamic and human sciences research. This necessity arises, on the one hand, from reductionist and superficial approaches to explaining hijab, and on the other, from the confrontation with anti-hijab discourses that challenge its epistemological foundations and multifaceted functions.

The main objective of this study is to present a comprehensive, well-documented, and innovative analysis of the various dimensions of the necessity of hijab, drawing upon authentic Qur’anic and hadith sources, rational foundations, psychological findings, and sociological analyses. Adopting an interdisciplinary and analytical-argumentative approach, the research critically and synthetically examines the diverse aspects of hijab by engaging both religious texts and credible scientific resources.

The findings indicate that hijab is not merely a legal-religious obligation, but rather a comprehensive system of values and behaviors intricately connected to an individual’s personality structure, the psychological well-being of society, family cohesion, and broader social functions. A multidimensional explanation of hijab thus enables a deeper and more convincing understanding of this divine injunction. The innovation of this study lies in integrating Qur’anic and hadith-based meanings with modern rational, psychological, and sociological analyses, offering a comprehensive framework for understanding the functions of hijab in the modern world.
