And Allah sets forth a parable: (Consider) a town safe and secure to which its means of subsistence come in abundance from every quarter; but it became ungrateful to Allah's favors, therefore Allah made it to taste the utmost degree of hunger and fear because of what they wrought.

And you see the mountains, you think them to be solid, and they shall pass away as the passing away of the cloud-- the handiwork of Allah Who has made every thing thoroughly; surely He is Aware of what you do.
