The sociology of religion focuses on an individual's social and married life. This research performed the first focalized examination of the influence of spirituality and religiosity on the marital satisfaction of Pakistani Muslim couples and how religious commitment and religious practice strengthens the relationship of married couples. This study incorporates the Kansas Marital Satisfaction scale (KMSS), the Religious Commitment Inventory (RCI-10) and the Religious Practice scale to measure marital satisfaction. Survey questionnaires, including a survey invitation letter and an informed consent form, were sent to married couples residing in five urban areas of Pakistan. The sample consisted of 508 valid responses, 254 males and 254 females, exploring the respondent's perception of their marital satisfaction. The data received were screened and tested through SPSS version 25. The first step of the data analysis was to examine the impact of religiosity variables (religious commitment, religious practice) on marital satisfaction. Findings indicated that religious commitment and religious practice are vital for a happy married life. The findings help explain the social dynamics of marital satisfaction in Pakistani culture. The results also indicated that religious commitment and religious practice strengthened and promoted marital satisfaction. This study is novel in the context of Pakistani culture and conclusions cannot be generalized to the whole population. Other religious factors may provide further research directions. The results of this study may help practitioners and decision-makers focusing on marital satisfaction issues.
