<![CDATA[The phenomenon of quarter-life crisis (QLC) is increasingly experienced by Generation Z, characterized by excessive anxiety, identity uncertainty, career pressure, and failure to achieve life targets at the age of 20–30 years. Conventional psychological approaches often only touch cognitive-behavioral aspects without reaching the spiritual dimension that is fundamental for the Muslim generation. This article aims to examine the integration of tazkiyatun nafs values (soul purification) within the framework of dakwah nafsiyah (self-directed da'wah) as an alternative holistic approach in dealing with QLC in Gen Z. This research uses a library research method by analyzing various primary sources in the form of Sufism books, scientific journal articles related to QLC and Islamic psychology, as well as data on the characteristics of Gen Z. The analysis technique used is qualitative content analysis with a descriptive-interpretative approach. The results show that tazkiyatun nafs values such as muhasabah (self-introspection), mujahadah (striving against lust), taubat (returning to Allah), and tawakkal (surrender to Allah) can be systematically integrated through the dakwah nafsiyah method consisting of ta'aruf (knowing oneself and Allah), tawajjuh (directing the heart to Allah), and tathbiq (application of values in daily life). This integration has proven to reduce existential anxiety levels, increase spiritual resilience, and form a God-based mindset in Gen Z. In conclusion, dakwah nafsiyah based on tazkiyatun nafs offers a comprehensive solution that not only cures QLC symptoms but also builds a strong Islamic personality foundation. This research recommends the need to develop structured dakwah nafsiyah intervention programs for the young Muslim generation.]]>
