The tradition of Tahlilan, Yasinan, and Marhabanan held on Friday night in Tegalgirang Village is a form of integration between Islamic teachings and local culture. These activities not only function as a means of worship, but also have important social and cultural values. The resulting virtues include: (1) strengthening friendship between residents through social interaction in the mushalla, (2) implementing the value of alms with the tradition of food banquets, and (3) prospering the mushalla as a center of culture and community education. This tradition is an effective medium in maintaining environmental harmony and strengthening Islamic noble values in the community.
