In the name of Allah, the Most Gracious, the Most Merciful,

The Messenger of Allah (salalahu ‘alayhi wa salam) said, "When Caesar is destroyed, there will be no Caesar after him, and when Kisra (a title designated to the emperor of Persia) is destroyed, there will be no Kisra after him. And by the One Who has my soul in His Hand, you will spend their treasures in the way of Allah." (Bukhaaree and Muslim) .This prophecy was fulfilled, for during the caliphates of Abu Bakr (radi allahu anhu) Umar  (radi allahu anhu), and Uthmaan (radi allahu anhu), Caesar (the name of this particular Caesar was Haraql) lost control of countries in Sham (Syria and surrounding regions) and the Arabian Peninsula. His dominion was then limited to the countries of Rome. In Arabic, the application of the word Qaisar (Caesar) was for he who ruled over Rome, Sham, and the Arabian Peninsula. Therefore this Hadeeth contained glad tidings for the inhabitants of Sham; it promised them that, until the Day of Judgment, they would never again be under the rule of Rome. As for Kisra, he lost his entire control of most of his dominion during the caliphate of 'Umar (radi allahu anhu), and then he lost everything during the caliphate of 'Uthmaan (radi allahu anhu). According to one narration, - this occurred in the year 32 H - all praise is for Allah and all blessings are from Him. When the Prophet (salalahu ‘alayhi wa salam) sent a letter to Kisra, inviting him to Islam, the latter tore it up. The Prophet (salalahu ‘alayhi wa salam) supplicated against him, invoking Allah (subhana wa ta’ala) to completely tear apart his empire, and that is in fact what happened.
