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.

13:33Is He who is watchful over the deeds of every soul? Yet they ascribe associates to God. Say, “Name them! Or are you informing Him of something on earth He does not know, or is it a show of words?” In fact, the scheming of those who disbelieve is made to appear good to them, and they are averted from the path. Whomever God misguides has no guide.
