I used the Arabic alphabet because this is the base of the alphabet that was adapted by the literate people of Iran in the 10th century CE, a different time and age when Arabs were not considered to be the enemies of Iranians. Your Umayyads, who were our enemies, had already been consigned to the dust-bin of history centuries before after Iranian peasants from Khorasan joined the Hashimiyya and revolted against, and then extinguished, these barbarian Umayyads. So our score had already been settled by the time Iranians finally decided that they could co-opt and adapt Islam to our own civilization and perspective, which is what we did much to the chagrin of modern Arabists.
You can write all the bullshit you want. Fact is, you either believe that Mohammad was a Prophet and that the initial Muslim expansion was a prophecy and blessing of Allah on Mohammad as his early companions, or you believe that Mohammad was just an Arab and that the Arab victories were one of pure luck that came just after the Romans and Persians had exhausted themselves during the 20 year war, making an Arab assault on the Middle East just after the great war an easy task as there was no real armies left on either side to resist their advance.
If you believe in the former, you obviously believe in the Islamic narrative. If you believe in the latter, then obviously you are not a Muslim and Islam to you is just an Arab invention and imperialism as those early victories were just Arab victories and not divine blessings on the Muslims. So which is it?
