13:1Alif, Lam, Meem, Ra. These are the signs of the Scripture. What is revealed to you from your Lord is the truth, but most people do not believe.

13:14To Him belongs the call to truth. Those they call upon besides Him do not respond to them with anything—except as someone who stretches his hands towards water, so that it may reach his mouth, but it does not reach it. The prayers of the unbelievers are only in vain.

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.

13:19Is he who knows that what was revealed to your from your Lord is the truth, like him who is blind? Only those who reason will remember.
