about your preventive warning Shouldn t you follow your own advice first In the al Khwarizmi page as well as al Biruni page you ve been exccessively edit happy You kept deleting legit sources I gave in the al Biruni page and in al Khwarizmi I have two sources that state that al Khwarizmi is an Arab you deleted it and kept Muslim since you don t have sources to prove he s Persian In the al Biruni page when I gave two more sources and cited one in the article it got prominently deleted why Is it because you have a problem with proof that he could ve been Arab Does that disturb the propaganda you re trying to spread Please take these nice policies and follow them before you start giving me preventive warnings WP V WP NPOV and WP NOR
