This paper examines the role of women in Islam concerning mosque attendance, exploring whether their access is full or restricted based on historical and textual evidence. The research reveals that while men's attendance is obligatory, women's attendance is optional but beneficial, reflecting a complex dynamic influenced by cultural practices and religious interpretations across different periods. It highlights the initial inclusive practices during the Prophet Muhammad's era and the subsequent restrictions introduced during the caliphate of Umar ibn Khattab, along with varying opinions among Islamic jurists on women's mosque attendance.
