This research discusses the construction of the Tahfidzul Quran Islamic Boarding School curriculum through social reproduction. The research methodology used in this study is qualitative descriptive research. By using the concept of Habitus as a structure of social reproduction, this study concludes that the curriculum at Ubay Bin Ka'ab Islamic Boarding School is constructed by reproducing ideologies, theological and moral beliefs, lifestyles adopted by lodge caregivers in particular and Tablighi congregational institutions in general. Although the curriculum focuses on memorizing the Quran, this pesantren teaches its students various religious knowledge and practices they need to participate in society as preachers. In addition, the curriculum also adjusts national education policies.
