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.
Do these rejectors not travel the earth and ponder over what the outcome was of the nations who rejected before them, and take heed from it? Those nations were wealthier, stronger and more influential than them in the world, but their actions and strength did not help them at all when the destructive punishment of Allah came.
