Indonesia has a majority Muslim population, but the population is not Arabic-speaking and the Arabic letters are not usually used except in religious contexts.[1] Therefore, to read the Quran in the original Arabic, Indonesian Muslims must learn Arabic letters and the pronunciations.[2] Some Arabic phonemes (such as /θ/ for ث) do not appear in Indonesian languages and take training to pronounce correctly.[3] In addition, students must also learn a special set pronunciation rules for Quranic recitation known as the tajwid.[4]
