Once when I was in Turkey I overheard a Turk saying he'd memorized the Koran, but since he didn't speak Arabic, he didn't understand it. He had to read the Koran in Turkish, but that's not the "official" Koran presented to Mohammed in Arabic.
Imagine if he was from Austria. According to the fraudster in the WH, he would be speaking Austrian.
( or was that people from Australia speak Australian?)
