Ar-Rum (Arabic: الروم, romanized: ’ar-rūm, lit. 'The Romans') is the 30th chapter (sūrah) of the Quran, consisting of 60 verses (āyāt). The term Rûm originated in the word Roman, and during the time of the Islamic prophet Muhammad, it referred to the Byzantine Greeks; the title is also sometimes translated as "The Greeks" or "The Byzantines".[1]

The surah provides information on how the cataclysmic Byzantine–Sassanid War of 602–628 looked to the Arabs of Mecca—interested onlookers who were still unaware that, within a single generation, they would enter the realm of imperialism and defeat both the Byzantines and the Sassanids.
