Hi graceoutcast
I cant read the first word (DOSTY), I think this is not Arabic language, I know its written in Arabic but it has no meaning for me. Yet may be its a slang language used in Afghanistan or a name of something there ( a city ..etc) sometimes a foreign word is written with Arabic words the way it is pronounced.
The middle word is Afghan. It is either an abbreviation of Afghanistan or if not an abbreviation it means Afghani (people of Afghanistan).
The third word is America.
So the whole sentence is (DOSTY)Afghan America

, the whole sentence have no meaning to me.
Sometimes Arabic words are used in different languages eg. Turkish and Indian but this doesn't mean that the language is Arabic. I don't know exactly what language they speak at Afghanistan but I think that Arabic is not their first language.
