True. During the Golden Age, most Persian scholars and scientists had to write their books in Arabic to preserve them in libraries. Most Persians had to choose Arabic names. That's why when people see a Persian mathematician like this one https://en.wikipedia.org/wiki/Muhammad_ibn_Musa_al-Khwarizmi, they might think he was Arab.

Fun fact: The word "Algorithm" comes from this guy's name!

He wasn’t Persian. This is a daylight robbery from the people of Central Asia. Look at his last name. Khwarazm is in Central Asia and it has no ethnic Persians(ethnic Tajiks don’t count).

The Wikipedia page literally says he was Persian. Khwarazm was part of Persia at the time.
