Have they not travelled in the earth and seen how was the end of those before them? They were stronger than these in prowess, and dug up the earth, and built on it in greater abundance than these have built on it, and there came to them their messengers with clear arguments; so it was not beseeming for Allah that He should deal with them unjustly, but they dealt unjustly with their own souls.

And We made between them and the towns which We had blessed (other) towns to be easily seen, and We apportioned the journey therein: Travel through them nights and days, secure.
