Persian influence was incredibly important, in fact the Islamic Golden Age is marked by Persian customs being absorbed into daily living with the establishment of the Abbasid caliphate.
So if you're feeling like it's taking value away from Persian history, instead, try to see it from the perspective that Persians are a large part of the reason why the Golden Age is even a thing :)
