Surah 89. Al-Fajr, Ayah 7

Iram would seem to have been an ancient 'Ad capital, in southern Arabia. It boasted of lofty architecture ("lofty pillars"). Some Commentators understand Iram to be the name of an eponymous hero of the 'Ad, in which case the following line, "with lofty pillars", should be construed "of lofty stature". The 'Ad were a tall race.
