Holy Quran » AL MU'MIN : 82

Have they not traveled through the land and observed how was the end of those before them? They were more numerous than themselves and greater in strength and in impression on the land, but they were not availed by what they used to earn.

{ أفلم يسيروا في الأرض فينظروا كيف كان عاقبة الذين من قبلهم كانوا أكثر منهم وأشد قوَّةً وأثارا في الأرض } من مصانع وقصور { فما أغنى عنهم ما كانوا يكسبون } .
