Compared to the other areas of South Asia, the conversion of the Maldives to Islam happened relatively late. Arab traders had converted populations in the Malabar Coast since the 7th century, and Muhammad Bin Qāsim had converted large swathes of Sindh to Islam at about the same time. The Maldives remained a Buddhist kingdom for another 500 years after the conversion of Malabar Coast and Sindh—perhaps as the southwesternmost Buddhist country. Arabic became the prime language of administration (instead of Persian and Urdu), and the Maliki school of jurisprudence was introduced, both hinting at direct contacts with the core of the Arab world.
