Response from Persian King To: Omar, "Khalifat of Islam Army".

http://www.zandiq.com/tazesh/ letter from Yazdgird 3(632 AD - 651 AD) The date in which this letter has been written is after the Battle of Ghadesiyeh. As you know, a natural disaster, a massive sand storm blown on Persian troops & practically blinded them & took their battle vision. the sand storm directly blown on their front & caused the loss of this battle. Later on Muslim Khalif mentioned that Allah sent the massive Sand Storm in Persian Faces, so they lost the battle, Allah was the protector of Muslim against Ajams (what Arabs call Persians). Battle of Ghadesiyeh did not just cost us a great loss due to a natural disaster, yet it also cost us the life of our greatest Persian Hero, Commander in Chief of Persian Army, General Arteshbod "Rostam-e Farokhzad." Tazis killed Rostam in this battle. Rostam & his squad fought until the last drop of their blood & at the end even after he lost his sword, he fought Arabs with bare hand & his shield, Rostam & his selected squad killed as many Tazi as they could, yet finally it was destiny for our hero to die for Iran. Tazi savages rushed & attacked him in all directions & killed that great Persian soul, Ahura Bless his soul, Rostam was the symbol of Persian Empire & Iranian Glory. Battle of al-Qādisiyyah : The first day of Battle ended with Persian advances and the Arab force appeared as though it would succumb to the much larger Sassanid army. In particular, the latter's war elephants terrified the Arab cavalry, and succeeded in creating confusion among the Arab fighters. By the third day of battle, Arab veterans of the Syrian campaign (being conducted nearly simultaneously) arrived on the scene and reinforced the Arab army. In addition, a clever trick -- whereby the Arab horses were decorated in costume -- succeeded in frightening the Persian elephants. When an Arab warrior succeeded in slaying the lead elephant, the rest fled into the rear, trampling numerous Persian fighters. The Arab Muslims continued to advance their attacks during the night (called the "Night of Clangour"). At dawn of the fourth day, a sandstorm broke out -- blowing sand in the Persians' faces. Quickly, the tide turned and the Sassanid centre gave way, particularly with the help of Arab archers. Rostam, who had been commanding his force from that location, killed and beheaded. Arabs announced the deed, displaying Rostam's head before the fighters, Seeing their respected leader's head dangling before them, the Persian fighters lost nerve and begin to flee. Most of the Sassanid fighters lost their lives in this melée, with a small number announcing their conversion to Islam. The Islamic conquest of Persia (633--656) led to the end of the Sassanid Empire and the eventual decline of the Zoroastrian religion in Persia. However, the achievements of the previous Persian civilizations were not lost, but were to a great extent absorbed by the new Islamic polity. Many historians have long offered the idea that Persia, on the verge of the Arab invasion, was a society in decline and decay and thus it embraced the invading Arab armies with open arms. This view is not accepted however. Some authors have for example used mostly Arab sources to illustrate that "contrary to the claims , Iranians in fact fought long and hard against the invading Arabs. This view further more holds that once politically conquered, the Persians began engaging in a culture war of resistance and succeeded in forcing their own ways on the victorious Arabs.[
