Background : Marital infidelity is one of the most distressing relational crises, with profound psychological and emotional consequences, posing significant challenges to relationship reconstruction . Despite extensive international research on forgiveness, there is a notable gap in Persian-language studies regarding the forgiveness process within Iran’s cultural and religious context, particularly considering the ethical teachings of Nahj al-Balagha .

Objective : This study aimed to explore and elucidate themes related to psychological factors and religion - based beliefs influencing the forgiveness process of marital infidelity in the lived experiences of Iranian women and men .

Methods : Using a qualitative approach and an inductive thematic analysis, the study included participants who had experienced spousal infidelity and had engaged in the process of forgiveness . Through purposive sampling, 14 participants (9 women and 5 men) were selected. Data were collected via semi-structured interviews averaging 60 minutes and analyzed using the seven - step Colaizzi method for coding and organization.

Results : Data analysis yielded seven main themes: the personality traits of the affected individual, beliefs about forgiveness, the importance of shared life, empathy, cognitive appraisals, religious beliefs, and the reactions of the unfaithful spouse. Concepts from Nahj al - Balagha were applied during the interpretation phase to deepen understanding of the extracted themes.

Conclusion: Findings indicate that forgiveness in Iranian society is not merely an emotional reaction but a gradual and meaning - centered process shaped by the interaction of psychological and religious factors. This process derives meaning through the lived experiences of individuals, with religious teachings such as those in Nahj al - Balagha providing supportive and interpretive guidance . Understanding this process can inform the design of culturally grounded interventions for couples affected by marital infidelity.
