Asalaam o'alaikom,wa alaykum salam,
Maybe sister Platina.- can help, although not sure about Tunisian. It is better to know Fus7a, the Arabic of the Qur'an, plus it is very similar to Modern Standard Arabic which is spoken throughout the Arabic speaking world.
Asalaam o'alaikom,
Sure i can learn you Fus7a, what Brother mabsoot said.
You need fus7a more,if you want to understand. the Qur'an ^ ^ And fus7a almost anyone can understand you in the Middle East or North Africa
Shokranlek Aghi Mabsoot
