Fun facts, there is a chapter in the Quran (Chapter 30) that is named Ar-Rum or The Roman, correctly refering to the Byzantine Empire at the time. It also correctly predicted the eventual loss of Persian Empire in one of the longest conflict world has ever witnessed that lasted for more than 600 years [1]. The prediction was against the run of events due to the fact that at the time of the revealation, Persian was on a winning streaks. The pagans of Mecca were rejoicing and mocking the Muslim on the defeats of the Roman, since they considered the Persian as idolators similar to them.

The Roman eventually won the war as predicted and victorious over the Persian in 627 AD under Emperor Heraclius in Nineveh, and at the same time the people of Madinah (at the time called Yathrib) were defeating their enemies of Arab alliances by digging the trench (khandaq) in Madinah using a military tactic made popular by the Persian. During the the khandaq war according to tradition, it was prophezied that the capital of Rome (Byzantine) at the time namely Constantinople will falls to Muslim. Eventually after more than 700 years of conflicts surpassing the duration of Roman–Persian Wars, and after many campaigns that started as early as 674 AD, Constatinople fell to Ottoman Empire in 1453 AD under Sultan Muhammad Al-Fatih [3],[4].
