This study examines the theological significance of the pilgrimage tradition at the sacred tomb of Mandeh Rubiah, located in Lunang, Pesisir Selatan Regency. This pilgrimage tradition persists among local communities and visitors from various regions due to its perceived religious, social, and spiritual value. The study aims to identify the rituals performed during the pilgrimage, the pilgrims' underlying intentions, and the theological meanings embedded within the practice. A qualitative method with a descriptive approach was employed, utilizing observation, interviews, and documentation. The findings reveal that the rituals include forming the intention to visit, performing wudu (ablution) for ritual purification, praying at the tomb, conveying supplications to Allah, and fulfilling previously made vows (nadzar). From a theological perspective, the pilgrimage tradition at the Mandeh Rubiah tomb holds several significant meanings: serving as a means to draw closer to Allah through prayer and worship, reminding individuals of death and the afterlife, and acting as an emotional outlet for those facing life's challenges. The novelty of this research lies in its theological analysis of the pilgrimage tradition at the Mandeh Rubiah tomb, integrating ritual aspects, pilgrimage objectives, and the community's religious interpretations into a comprehensive study. Unlike previous research which typically focused solely on historical, cultural, or practical aspects this study emphasizes how the tradition is understood as an expression of the community's faith and spirituality. The study contributes to the fields of Islamic theology and religion-culture studies by elucidating the relationship between local religious practices and theological values, while also serving as a reference for future research on pilgrimage traditions and local wisdom from a theological perspective.
