The Truth vs Falsehood
13:17 He sends down water from the sky, causing the valleys to overflow, then the rapids produce abundant foam. Similarly, when they use fire to refine metals for their jewelry or equipment, foam is produced. GOD thus cites analogies for the truth and falsehood. As for the foam, it goes to waste, while that which benefits the people stays close to the ground. GOD thus cites the analogies.
13:18 Those who respond to their Lord deserve the good rewards. As for those who failed to respond to Him, if they possessed everything on earth—even twice as much—they would readily give it up as ransom. They have incurred the worst reckoning, and their final abode is Hell; what a miserable destiny.
