Iran is recognized as the top state supporter of terrorism. They aren't Arabs, and their brand of Islam is Shia, not Sunni. So there are plenty of bad actors out there. But you do bring up an important point, Arab influence on the spread of Islam. The Saudi's are supporters of the Wahabbists. Their schools have infected populations throughout the Muslim world outside of Iran's influence. Particularly in Pakistan.
Iranians also speak Farsi, not Arabic.
