In northern Sumatra, Samudera Pasai became one of the earliest Muslim trading kingdoms with strong evidence of Islam by the late 1200s. Accounts of the sultanate describe its adherence to the Shafi‘i madhhab, making Pasai an early Southeast Asian center where Islamic law could be taught and practiced through court and port life.
By the 1300s, Muslim merchants and scholars were linking ports from the Red Sea and India to Southeast Asia. These ocean networks helped carry Islamic legal learning (fiqh) alongside trade, creating pathways for the Shafi‘i school to become influential in maritime Southeast Asia.
Around 1400, the Malacca Sultanate formed on the Malay Peninsula and rapidly grew into a major entrepôt (trading port) on the Strait of Malacca. Malacca’s court and commercial influence helped spread Islamic institutions and norms across connected ports, including legal ideas that later shaped Malay legal writing.
During the reign of Sultan Muhammad Shah (1424–1444), Malacca’s court began compiling what became the Undang-Undang Melaka (Laws of Malacca). The code blended Malay customary law (adat) with Islamic principles, creating an influential model for how Shafi‘i-oriented ideas could be adapted into local governance and courtroom practice.
From the mid-1400s into the early 1500s, Malacca’s legal digest was expanded by later rulers and copied beyond Malacca. Its spread mattered because it provided other sultanates with a ready-made framework for Islamic-tinged law in Malay, supporting wider acceptance of Shafi‘i legal norms in administrative life.
In 1511, the Portuguese conquered Malacca, disrupting the region’s leading Muslim port-state. Political and scholarly energy increasingly shifted to other Malay and Sumatran courts and port cities, where Shafi‘i legal teachings continued through new centers of patronage.
In the 1600s, the Aceh Sultanate became a key place where Islamic scholarship was supported by rulers and connected to wider Muslim networks. Aceh attracted scholars who taught Sunni theology, Sufism, and Shafi‘i jurisprudence, strengthening the role of court-sponsored learning in legal and educational transmission.
Nur al-Din al-Raniri, a Shafi‘i jurist-scholar active at Aceh’s court, authored al-Sirat al-Mustaqim, an early Malay-language work of fiqh focused largely on worship practices. A widely read text in the region helped standardize Shafi‘i guidance in a language and script accessible to Malay readers and students.
Abd al-Rauf al-Singkili left for Arabia around 1642 and studied for about two decades, connecting with prominent teachers and scholarly networks. His training and later teaching illustrate how Southeast Asian scholars used pilgrimage-and-study routes to bring Shafi‘i legal learning back into local institutions.
Aceh’s ruler Safiatuddin (r. 1641–1675) requested Abd al-Rauf to prepare Mir’at al-Tullab, a substantial Malay fiqh work aligned with the Shafi‘i school. This court commission linked state authority, education, and Islamic law, and surviving manuscript copies across libraries show how the text traveled beyond Aceh.
Over time, Malay courts produced and adapted legal digests that mixed adat with Islamic legal ideas, often drawing on Malacca’s models. This repeated copying and revising helped embed Shafi‘i-oriented legal concepts into everyday governance and dispute resolution across different parts of the Malay world.
In the late 1700s, Muhammad Arsyad al-Banjari of South Kalimantan produced Sabilal Muhtadin, a major Shafi‘i fiqh text associated with the Banjar region. The work shows a later phase of transmission: Shafi‘i law was not only imported but also written locally to address regional practice, strengthening the madhhab’s long-term authority in Southeast Asia.
