Aceh Sultanate
Islam is believed to have spread in lands of the Singkil people a few centuries ago by foreign merchants that came from Minangkabau Highlands and later during the rule of the Aceh Sultanate. Many of the Minangkabau people have left traces of their history and their descendants in the coastline region. Abdurrauf Singkil, also known as Syekh Abdur Rauf as-Singkili was once a famous Singkil ulama that was appointed as a head ulama and a mufti in the Acehnese kingdom in 17th century.
