This chapter discusses the influence of Ottoman Qur’ans on the Qur’an in Southeast Asia, from the manuscript era and through the period of early printing up to the present day. At various times, Ottoman influence can be detected in certain specific aspects of Southeast Asian Qur’ans, including illumination and calligraphy, and in particular in the adoption of the Ottoman ayet ber kenar model of page layout. Special attention is paid to the Qur’an lithographed in Palembang in 1848, as the earliest Qur’an printed in Southeast Asia. In recent years Ottoman influence has become much stronger, particularly since the ratification of the Indonesian Standard Qur’an in 1984, as one of the three approved versions is based on the Qur’an printed at the Matbaa-i Bahriye in Istanbul. This edition of the Qur’an has long been used in Indonesia by Qur’anic reciters, who learn the text by heart (ḥāfiẓ) in various pesantren (madrasas).
