The coming of Islam in the Buton Sultanate has brought a change in the social, political, even in the intellectual aspects. It produced scholars with the thought or ijitihad as a blend of Islamic and local cultures. One of the scholars as well as Buton Sultan was Muhammad Idrus Kaimuddin Ibnu Badaruddin Al Buthuni (1824-1851). His thought or ijitihad found the essence of the concept of manners according to the teachings of the ancestors in kabanti Bula Malino. His several works became the guidance of the public and court authorities in the Sultanate of Buton which were basically rooted from the teachings of Islam. Kaimuddin’s thought in terms of ethics, morals, manners, or advice showed his horizons of knowledge and the depth of leadership thought. The magnitude of Islamic influence in some of his works proves the enduring process of Islamic acculturation done continuously and deeply since the era of Buton Islamic empire. Kaimuddin’s thought is essentially a formation process of Buton’s civilization centered on the palace and passed to Buton society in general through the process of cultural dialogue between Buton culture (Wolio) and Islam.
