And this is a Book We have revealed, blessed, verifying that which is before it, and that you may warn the metropolis and those around her; and those who believe in the hereafter believe in it, and they attend to their prayers constantly.

And We have not sent before you but men from (among) the people of the towns, to whom We sent revelations. Have they not then travelled in the land and seen what was the end of those before them? And certainly the abode of the hereafter is best for those who guard (against evil); do you not then understand?

And how many a town which was iniquitous did We demolish, and We raised up after it another people!
