(Al-Fajr) 89 : 8
الَّتِي لَمْ يُخْلَقْ مِثْلُهَا فِي الْبِلَادِ
The likes of which had never been built in cities.
This means the high constructions built by the people of Aad were never built anywhere in the land at any time. It is particularly notable that the buildings seen in this period are constructed with the help of new technologies, including cranes, other equipment, and machinery. See explanation 41: 15.
