A place mentioned in the Qur’an, Surah lxxxix. 6: “Iram of the columns, the like of which has not been created in these land.”
It is related that ash-Shaddad, the son of ‘Ad, ordered the construction of a terrestrial paradise in the desert of ‘Adan, ostensibly to rival the celestial one, and to be called Iran after his great grandfather. On going to take possession of it, he and all his people were struck dead by a noise from heaven and the paradise disappeared.
