Based on focus group discussions, the findings revealed dual trend, while some youth demonstrate stronger faith, discipline in practicing Islam, and religious tolerance, others develop signs of exclusion attitudes and rigid interpretation of Islam labelled as extremism, perceived in relation to lake of empathy, rigidity, and accusative tone but not as violence. Core themes include shaping of digital religious identities, peer influence, algorithmic exposure to Islamic content, and skepticism towards celebrity scholars and organizations on YouTube. The study highlights key implications for religious educators, media regulators, and policymakers and contributes to understand digital religion in South Asia.
