Heja Helwada offered cited references that Khorasan had huge immigrations from Arab families. I offered many references that state him to be an Arab. Logically, these are better than a potentially bogus poem you posted.
   Three legit sources that al-Khwarizmi was Arab
   References that Khorasan had a huge immigration by Arabs.
    Nothing but claims that al-Khwarizmi was Persian

You gave us zero references that state him to be explicitly Persian, not only that but you also tried to veer this off to a discussion on the political/historical background of Khwarizm. What do we conclude from your(and other Iranian editors') actions so far?
