The family, as the most fundamental social institution, faces serious communication challenges in the modern era. A deficiency in communication skills is considered one of the primary factors in the instability and dissolution of this institution. This research aims to elucidate a model of interpersonal communication derived from the words and conduct (Seerah) of Imam Reza (A.S.) and its role in consolidating family relationships. The main research question is: which behavioral components in the Razavi tradition can guide the improvement of interpersonal relationships within the family nucleus? Employing an analytical approach and a library research method, this study scrutinizes narrative and historical sources related to the conduct of Imam Reza (A.S.), aligning them with modern theories of human communication. The findings indicate that the Razavi teachings encompass components such as “creating a safe space for dialogue,” “affectionate behavior,” “respect for personal dignity,” “audience awareness,” “justice in conduct,” and “self-grooming.” These components, which can be analyzed within the conceptual framework of the “Five-Dimensional Communication Model” (comprising openness, empathy, supportiveness, positivism, and equality), demonstrate a remarkable structural congruence with theories such as Habermas’s “Public Sphere.” The conclusion is that the application of this behavioral model can lead to the establishment of tranquility, the enhancement of intimacy, and the reduction of conflicts within the family. It can, therefore, be utilized as an effective strategy for confronting communication crises.
