Holy Quran:
34:18 We placed between them and between the towns that We blessed, towns that were easy to see; and We measured the journey between them: "Travel in them by night and day in complete security."
34:19 But they said, "Our Lord, make the measure between our journeys longer," and they wronged themselves. So We made them a thing of the past, and We scattered them into small groups. In this are signs for every person who is patient, thankful.
