Iranians where considered Aryans by Hitler, in fact the term Aryan comes from old iranian Arya.

The Nazis advocated the common Aryan ancestry of Iranians and Germans. As a result, in 1936 the Reich Cabinet issued a special decree exempting Iranians from any restrictions to the Nuremberg Racial Laws on the grounds that they were "pure" Aryans. Various pro-Nazi publications, lectures, speeches, and ceremonies, also drew parallels between Reza Shah, Hitler, and Mussolini to emphasize the charismatic resemblance among these leaders.
