Iram of the Pillars (إرَم ذَات ٱلْعِمَاد, ; an alternative translation is Iram of the tentpoles), also called "Irum", "Irem", "Erum", "Ubar", or the "City of the pillars", is considered a lost city, region or tribe mentioned in the Quran. The Quran mentions Iram in connection with ‘imad (pillars): Surah al-Fajr (6-14) 6: Have you not considered how your Lord dealt with ‘Aad – 7: [With] Iram – who had lofty pillars, 8: The likes of whom had never been created in the lands 9: And [with] Thamud, who carved out the rocks in the valley? 10: And [with] Pharaoh, firm of might? – 11: [All of] whom oppressed within the lands 12: And increased therein the corruption. 13: So your Lord poured upon them a scourge of punishment. 14: Indeed, your Lord is in observation. There are several explanations for the reference to "Iram – who had lofty pillars". Some see this as a geographic location, either a city or an area, others as the name of a tribe. Those identifying it as a city have made various suggestions as to where or what city it was, ranging from Alexandria or Damascus to a city which actually moved or a city called Ubar. As an area, it has been identified with the biblical region known as Aram. It has also been identified as a tribe, possibly the tribe of ʿĀd, with the pillars referring to tent pillars. The Nabataeans were one of the many nomadic Bedouin tribes who roamed the Arabian Desert and took their herds to where they could find grassland and water. They became familiar with their area as the seasons passed, and they struggled to survive during bad years when seasonal rainfall decreased. Although the Nabataeans were initially embedded in the Aramean culture, theories that they have Aramean roots are rejected by modern scholars. Instead, archaeological, religious and linguistic evidence confirms that they are a North Arabian tribe. "The identification of Wadi Rum with Iram and the tribe of ʿĀd, mentioned in the Quran, has been proposed by scholars who have translated Thamudic and Nabataean inscriptions referring to both the place Iram and the tribes of ʿĀd and Thamud by name.
