The story of Bahlul in acting. For Arabic practice.
Now Trukish series are popular among BDers. But I can't think of watching those. First the stories are all made up, and not based on history. Second I see no point in learning Turkish along with all the other languages that we have to learn. Arabic, English, Bengali and Urdu should be enough.
