This study examined cross-sectional links of the theistic and non-theistic sanctification of marriage and positive and negative religious coping with marital adjustment for 316 married Muslims from Iran. Perceiving marriage to be a manifestation of God and reflective of sacred qualities as well as engaging in positive and negative religious/spiritual coping strategies each uniquely contributed variance to marital adjustment, after controlling for each other and global indicators of devotion to Islam, and demographic variables. Specifically, theistic sanctification, non-theistic sanctification, and positive (...) r/s coping were uniquely tied to higher marital adjustment whereas negative r/s coping was uniquely tied to lower marital adjustment theistic in a hierarchical regression model with all primary variables and controls entered. These findings replicate and extend prior findings on the perceived sanctity of marriage with US samples of predominantly Christians to Muslims living in the Middle East, and offer novel cross-cultural insights into the possible roles that sanctification of marriage and r/s coping may play for marital well-being for non-distressed married Muslims.
