13:17He sends down water from the sky, and riverbeds flow according to their capacity. The current carries swelling froth. And from what they heat in fire of ornaments or utensils comes a similar froth. Thus God exemplifies truth and falsehood. As for the froth, it is swept away, but what benefits the people remains in the ground. Thus God presents the analogies.

13:35The likeness of the Garden promised to the righteous: rivers flowing beneath it; its food is perpetual, and so is its shade. Such is the sequel for those who guard against evil, but the sequel of the disbelievers is the Fire.

13:41Do they not see how We deal with the earth, diminishing it at its edges? God judges; and nothing can hold back His judgment. And He is quick to settle accounts.
