Examining jurisprudential texts shows examples of women's rights that are less known in customary norms and legal sources. This is despite the fact that after the victory of the revolution, the adaptation of the laws to the rules of Islam and the realization of the material and spiritual rights of women were emphasized in the principles of the constitution. However, the examination of customary norms and legal articles shows their incompatibility with Sharia rights and as a result, women's rights are violated in the society. This article tries to introduce the reasons for this gap. For this purpose, 30 women living in Tehran province, who had a history of married life, were interviewed using the purposeful and theoretical sampling method, and the findings were analyzed with a critical grounded theory approach. Finally, 11 key categories were extracted, among them "the hegemony of the male-centered collectivist culture" and "the culture that governs the couple's family" as background conditions and "men's exclusivity", "women's lack of demands" and "inappropriate interactions between couples" were identified as the causal conditions of this gap. The main concern of the interviewed women was "conflict of asserting rights and maintaining stability or peace in the family" which was influenced by the intervening conditions of "expenses and expansion of patronage", "social disturbances" and "characteristics of the couple". Actions of "compliance or non-compliance with the violation of rights" lead.
