The Marriage is Scary phenomenon represents the fear of the young urban generation towards the institution of marriage which is considered no longer able to guarantee happiness, stability, and relevance to contemporary reality. This study aims to analyze the phenomenon through the lens of Jean-François Lyotard’s postmodernism, examine the underlying social factors and shifts in values, and analyze the implications for the understanding of marriage within Islamic legal philosophy, drawing upon maqāṣid al-sharī‘ah and the thought of Fazlur Rahman.. Using qualitative-descriptive methods and an Islamic legal philosophy approach, this study explores how the postmodern deconstruction of moral and religious metanarratives causes the meaning of marriage as a sacred institution to begin to be questioned. The results of the analysis show: First, Lyotard's concept of incredulity toward metanarratives explains the shift in societal orientation towards more individualistic values that the Marriage is Scary phenomenon is a symptom of weakening trust in grand narratives, including religious and moral values that once made marriage a sacred institution. Second, this fear of marriage encourages the emergence of individualistic mindsets, delays in long-term commitments, and an increased preference for informal relationships that are considered more flexible. Third, the noble purpose of marriage within the framework of the maqasid al-syari'ah, particularly ḥifẓ al-nafs, ḥifẓ al-‘irḍ, dan ḥifẓ al-nasl, is no longer read as a living moral vision, but merely a normative doctrine. This research confirms that postmodern criticism of the narrative crisis can be used as momentum to reformulate a more substantive understanding of Islamic family law.
