This publication project which we endeavoured; in collaboration between PERGAS (Singapore Islamic Scholars & Religious Teachers Association & MUIS (Islamic Religious Council of Singapore), tracks a record of the vast contributions of Islamic religious leaders in Singapore, who consist of religious teachers (asatizah), scholars, and Muslim leaders. They helped in spreading the message of Islam, served as beacons of knowledge and were at the heart of the development of Islam in Singapore from as early as the 15th Century.
