Umm, I don’t think so. Roman empire fell in 476. Islam wasn’t invented until about 200 years later.
“Roman empire fell in 476. Islam wasn’t invented until about 200 years later.”
Muslims defeated the Romans in Persia. Their conquest led to the end of the Sassanid Empire in 644, the fall of Sassanid dynasty in 651 and the eventual decline of the Zoroastrian religion in Persia. Following the transfer of Khalid to the Roman front in the Levant, the Muslims eventually lost their holdings to Persian counter-attacks
