And the parable of those who spend their property to seek the pleasure of Allah and for the certainty 'of their souls is as the parable of a garden on an elevated ground, upon which heavy rain falls so it brings forth its fruit twofold but if heavy rain does not fall upon it, then light rain (is sufficient); and Allah sees what you do.

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.
