This paper is the result of a qualitative study through observation and interviews under the theme of the religious life of indigenous communities of Suku Anak Dalam in Dusun Senami III, Jebak village, Kabupaten Batanghari. Although Suku Anak Dalam still embrace traditional beliefs, but they also understand that the teachings of Islam are the teachings of the sacred, containing rules, commands and prohibiton that in line with their customs. The study also found that it is still difficult for them to make Islam as something that could be internalized in their everyday life. Keywords: kehidupan keagamaan, Suku Anak Dalam, Desa Jebak.
