<![CDATA[The Bakampuang Ampek Suku Tradition in the engagement procession (Khitbah) in Nagari Lubuak Alai, Kapur IX District, 50 Kota Regency. In the midst of the modernization era, this tradition remains firmly established as an instrument of social control and integration of local communities based on the customary principle of basandi syarak, syarak basandi kitabullah. The study aims to determine the process of implementing the Bakampuang Ampek Suku Tradition in the engagement and to analyze the tradition based on the perspective of maslahah. This study uses a qualitative method through field research. Primary data were obtained directly from informants in the field such as the Village Head, Head of Kan, Niniak Mamak, and the Community. Secondary data are supported by bibliographic books, journals. Data collection techniques were carried out through structured interviews, observation, and documentation. The results of the study show that firstly, the implementation of the Bakampuang Ampek Suku tradition consists of four structured stages, namely the family marundiang (rundiang paruik), menyilau/mambuek tando, Bakampuang kaum, and Bakampuang Ampek Suku, which involve elements of the niniak mamak from the four tribes, religious scholars, cadiak pintar, and village officials. This forum discusses the logistical readiness of the party, genealogical validation to prevent inter-tribal marriages, and the determination of customary sanctions in the form of rompak paga for prospective brides from outside the region. Secondly, from the perspective of maslahah, the Bakampuang Ampek Suku tradition brings benefits (manfa'ah) and repels harm (mafsadah). Therefore, this tradition does not contradict the Qur'an and Hadith.]]>
