The first evidence of Indonesian Muslims comes from northern Sumatra; Marco Polo, on his way home from China in 1292, reported at least one Muslim town;[13] and the first evidence of a Muslim dynasty is the gravestone, dated AH 696 (AD 1297), of Sultan Malik al Saleh, the first Muslim ruler of Samudera Pasai Sultanate, with further gravestones indicating continued Islamic rule. The presence of the Shafi'i school of thought, which was to later dominate Indonesia, was reported by Ibn Battuta, a Moroccan traveller, in 1346. In his travel log, Ibn Battuta wrote that the ruler of Samudera Pasai was a Muslim who performs his religious duties with utmost zeal.
