Data were conducted toward observation of Sumbahyang
Ampek Puluh activities in 7 Mosques in Sijunjung region during Ramadan Month in 2018 and
interviews with several preachers and women of Sumbahyang Ampek Puluh members. Qualitative
data analysis was conducted descriptively towards reduction, display and verification. The results
show that Sumbahyang Ampek Puluh is dominantly followed by women. These women are at the
age of menopause but economically it is still very productive. During the day they work in the fields,
gardens, stalls and at night, they stay in the mosque to pray in congregation, pick up the
congregational prayers that are left behind, read and study the Qur'an, study Fiqh, interpret the
Qur'an and the problems of monotheism, never leave the prayer in congregation, stay away from
immoral acts and try to get closer (taqarrub) to Allah like men.
