Retard. The prophet sent a message to the Byzantine emperor Heraclius and the Shahanshah of Persia, inviting them to join Islam. There is evidence that they rejected the invitation, such as the Shah tearing down the letters and insulting Muslim envoys. The Prophet then predicted that their empires would crumble in the same way they had torn down his message. This prediction came true, as the Persians were the first to be obliterated by the Muslims during early conquests, while the Byzantines survived for another 1000 years.
