March  UTC  Actually I gave two both of which are encyclopedias Your source says persianborn Heja Helwada provided sources that there were a large number of Arabs in Khwarizm You gave me no sources from Columbia encyclopedia also you provided no sources to prove that the alleged poem was written by the Arab scientist alBiruni Encyclopedia Iranica states that there were huge immigrations by Arabs to the region proving that not everyone from Khwarizm was Persian Please stop disregarding tangible evidence
