Although Benda Village, Sirampog District is an area that upholds high religious social values because it is located in the Islamic boarding school environment. However, the concept of kafa'ah that is applied is not only based on religious similarities. There are several criteria that are considered important also in choosing and determining a partner. Among them are similarities in work, nasab, property, education and physical. This similarity does not contradict the concept of kafa'ah stipulated in Islam. But sekufu in religion becomes the first and foremost measure. This concept is clearly believed and applied as a logical consequence of Islamic law. In addition, being in the Islamic boarding school environment also has an influence on the selection of religion as the first and main order in choosing and determining a partner.
