The primary goal of this study is to open various windows into Islamic religious thought in the Malay-Indonesian world over a period of around seven centuries, commencing with the establishment of Islam in the region during the latter part of the 13th century, and continuing on until the present day. This work may arouse interest in Muslim Southeast Asia in both academic and general circles. Similarly, it is hoped that the present study will be applicable in western academic contexts where studies of Southeast Asia are being conducted. It should prove to be a useful reference for undergraduate studies focusing upon Indonesia, Malaysia, Thailand and the Philippines. It may also be of interest to Islamic and Middle East Studies.
