 :Im reverting back. You cannot claim that western sources are "weak" and "liars". Zora provided several sources supporting what is written. So did I. The best you can do is add any opposing sources to the text. Not delete anything. Your post obviously demonstartes you are Sunni, and a supporter of Umar. But you are not the only person who knows Arabic here. There is specific mention of Arab cruelty against mawali in: 

 #Al`Allamah Baqir al-Majlisi, Bihar al-'anwar, vol. 9, chap. 124. 
 #Shaykh 'Abbas al-Qummi, Safinat al-Bihar, (under wall), c.f. al-Kay. 
 #al-Khutat by al-Maqrizi. e.g. "See that not a single person in Iran speaks Arabic, and whosoever is found speaking Arabic kill him". 
 #Ibn an-Naqqash, Fatwa concerning the condition of the dhimmis, vol. 18, pp. 513-514, trans. Belin, Journal Asiatique, Vol. 18 (1851) and Vol. 19 (1852); in B. Ye'or, The Dhimmi: Jews and Christians Under Islam, pp. 184-185
