Marriage and familly constitute One of the foundamental teachings of Islam. The aim of marriage is to bring about peace and quiet among men and women, in the light of which they can improve and reline their morals and train their children wrrectly. It goes without saying that one can attain that aim only through understanding, compatibility, spiritual and intellectual sameness, moral and epistemic harmony among couples. An analysis of the concept of kafa ‘at (compatibility) and Qur’anic and narrative criterion in this regard from the viewpoints of the Muslim jurists suggests that the only factor behind a successful marriage and righteous family, apart from wealth, beauty. knowledge etc. is to take into account the criterion of religion in marriage. Most social psychologists, following their empirical investigations put emphasis on compatibility in marriage.
