Following the triumph of the Islamic Revolution in Iran, the concept of lifestyle has assumed paramount importance, particularly through the Supreme Leader’s recurrent emphasis on revitalizing Islamic lifestyle while countering Western paradigms. This study investigates the underlying causes and mechanisms facilitating the dissemination of Western culture—rooted in consumerism, hedonism, individualism, luxury-seeking, and capitalism—and its deleterious effects on Islamic lifestyle in Iran. Drawing upon the Supreme Leader’s statements and Quranic verses, the research employs a descriptive, library-based methodology to analyze these dynamics. Findings reveal that Western lifestyle, propagated via cultural instruments (e.g., cinema, music, toys), mass media (e.g., television, literature), and communication technologies (e.g., internet, social networks), constitutes a form of cultural invasion antithetical to Islamic principles, eroding religious values, familial bonds, and national identity. This infiltration fosters moral decline, social fragmentation, and psychological insecurity, undermining the Quranic ideal of “ḥayāt ṭayyibah” (a good life) predicated on faith and righteous deeds. The study advocates for comprehensive strategies, including cultural fortification, media regulation, and adherence to indigenous Islamic wisdom, to safeguard Iran’s socio-cultural integrity and advance a new Islamic civilization. |
