Covering and Hijab's problem after the Islamic Revolution's victory has always been one of the most critical challenges of the Islamic Republic, especially in youth, students, and society's elite. The present study investigates the crucial doubts and questions about the Hijab and expresses scientific and convincing solutions and answers with the analytical-descriptive method and library resources. While describing the history of the Hijab in Islam and the Islamic Revolution of Iran, the present study responds to the vital and new suspicions that have recently been raised by opponents of the Hijab and some anti-Islamic media. Doubts are as follows: the conflict between the Hijab and the freedom and progress of women, the lack of connection between the Hijab and innocence, the different perceptions of Muslims about the Islamic Hijab, the incorrect citation of the legality of the Hijab, etc.. Based on the results, the Islamic Hijab has no conflict with freedom (in its real sense) and never hinders the individual's growth, perfection, and maturity. Innocence and modesty accompanying Hijab can strengthen family privacy and lead to society's intellectual and spiritual health. All Islamic jurists agree on the necessity of the Hijab. There should be no confusion between the decisions of the rulers of Islamic countries and the people's behavior about Hijab, with the exact order of Islam that it is necessary to observe Hijab.
