I don't know what you expect from a source, there's a very good chance that you don't know Farsi. The title of that video,
رهبر انقلاب به ملکوت اعلی پیوست
Roughly translates to "the leader of the revolution joined the great kingdom."
The ad was in Farsi, so that checks out. Maybe they're assuming Iranians are trying to learn Arabic because basically every country around them does?
