Is it wise to submit sound files in non-English speaking languages? I mean it might be for the sake of foreign people who come to this site. The only files I know of that are in Arabic are in The Last Express.
We have indeed submitted voice clips in foreign languages. Random Talking Bush's most recent submission, Breath of the Wild, has clips in all sorts of different languages.
In that case, I see no reason why not too.
If you're submitting a game's voice files, you should always include any ones in alternate languages too, if for no other reason than completeness (and as Twister said, for usability for speakers of these languages).
