The Qur'an includes the Surat Ar-Rum, the sura dealing with "the Romans", sometimes translated as "The Byzantines," reflecting a term now used in the West. These Romans of the 7th century, referred to as Byzantines in modern Western scholarship, were the inhabitants of the surviving Eastern Roman (Byzantine) Empire. Since all ethnic groups within the Roman empire had been granted citizenship by 212 AD, these eastern peoples had come to label themselves Ρωμιοί or Ῥωμαῖοι "Romaioi" (Romans), using the word for Roman citizen in the eastern lingua franca of Koine Greek. This citizenship label became "Rûm" in Arabic. To differentiate the inhabitants of the western city of Rome the Arabs used instead the word "Rūm" or sometimes "Latin'yun" (Latins), and to differentiate ancient Greek speakers the term "Yūnānīm" was used from "Yūnān" (Ionia), the name for Greece. The word "Byzantine," which is now used by Western historians to describe the Eastern Roman Empire and its Greek lingua franca, was not used anywhere at the time.
