Say, "Who is Lord of the heavens and earth?" Say, " Allah ."
Say, "Have you then taken besides Him allies not possessing [even] for themselves any benefit or any harm?"
Say, "Is the blind equivalent to the seeing? Or is darkness equivalent to light? Or have they attributed to Allah partners who created like His creation so that the creation [of each] seemed similar to them?"

He sends down from the sky, rain, and valleys flow according to their capacity, and the torrent carries a rising foam.

As for the foam, it vanishes, [being] cast off; but as for that which benefits the people, it remains on the earth.
Thus does Allah present examples. Ar-Ra'd 16-17
