Rohingya Muslims practise Sunni Islam of the Hanafi school, with a strong devotional layer expressed in the visiting of shrines, the observance of mawlid and the reciting of poetry in praise of the Prophet. The religious infrastructure of northern Rakhine State before 2017 included mosques, madrasas and Quran schools in Rohingya villages, and religious teachers held authority in community life alongside village elders.
The Rohingya language is Indo-Aryan and closely related to Chittagonian, and it has been written at different times in Arabic script, in a Latin orthography, and in a purpose made script devised in the twentieth century. Religious instruction has generally been conducted in Arabic and in Urdu or Bengali, and the absence of a settled writing system for the language itself is one reason so little of the tradition has been recorded in it.
Rakhine, historically Arakan, has been a Muslim and Buddhist frontier for centuries. The Mrauk U kingdom, Buddhist and ruling from the fifteenth to the eighteenth century, used Persian court titles and issued coins carrying the Muslim declaration of faith, which is clear evidence that a Muslim presence there is old, however sharply the question of who descends from whom is now argued.
