Surah Taha (20:128): "Has it not become clear to them how many generations We destroyed before them, in whose ruined dwellings they now walk? There are signs in this for those with understanding".
Castles and Keeps which once upon a time were impenetrable. None could enter save for a few by the permission of their king. Now for a few pennies any riffraff off the street can visit the private chambers of the king.
Some build their forever homes here, yet when they cross dimensions they cant take it with them. There are no walls which can halt death.
"Whoever scatters his concerns among the matters of the world, it does not matter to Allah in which valley he meets his demise." - Sunan Ibn Majah
