Surah 22. Al-Hajj, Ayah 45

The roofs fell in first, and the whole structure, walls and all, came tumbling after, as happens in ruins. The place was turned upside down.

In a dry country like Arabia, a well stands as a symbol for a living, flourishing population, and many place-names mean "the well of so-and-so" e.g., Bir 'Ali, a village just south of Madinah the quality of whose drinking water is famous, or Abyar Ibn Hassan, a noted stopping place on the road from Makkah to Madinah about 92 miles from Madinah.
