Sarcasm, which is often used as a form of joking humor or criticism, can have a negative impact on interpersonal communication and individual mental health. This study aims to examine how the Tadzkiroh & Khotmul Qur'an program internalizes religious values in order to reduce sarcasm among Generation Z. This research uses a qualitative descriptive approach method with the type of case study conducted at SMA Informatika Serang City. Data were collected through in-depth interviews and program observations. The results showed that the internalization of religious values such as responsibility, honesty, empathy, and mutual respect and compassion in the Tadzkiroh & Khotmul Qur'an program includes three stages; value transformation, value transaction and value internalization which contribute to the prevention of sarcasm behavior among students.
