There is a scarcity in Teaching schools or individual teachers in Arabic Language.
The leading school is SEM in Tripoli-Lebanon, followed by the newly founded School of St. Romanos in Homs-Syria. Needless to mention the first school which is the College of Theology at the University of Balamand in Lebanon.
These schools offer a structured course and method in teaching Byzantine Music in Arabic, keeping in mind that I'm only talking about the Orthodox Church of Antioch.
Other Chanters and ordained readers in each church.
