Do you not see that Allah drives along the clouds, then gathers them together, then piles them up, so that you see the rain coming forth from their midst? And He sends down of the clouds that are (like) mountains wherein is hail, afflicting therewith whom He pleases and turning it away from whom He pleases; the flash of His lightning almost takes away the sight.

Do they not consider that We have made the night that. they may rest therein, and the day to give light? Most surely there are signs in this for a people who believe.

Say: Tell me, if Allah were to make the day to continue incessantly on you till the day of resurrection, who is the god besides Allah that could bring you the night in which you take rest? Do you not then see?

Have you then considered him who takes his low desire for his god, and Allah has made him err having knowledge and has set a seal upon his ear and his heart and put a covering upon his eye. Who can then guide him after Allah? Will you not then be mindful?
