Ar-Ra'd 13:17

<h2>Two Parables proving that Truth remains and Falsehood perishes</h2><p>This honorable Ayah contains two parables which affirm that truth remains and increases, while falsehood diminishes and perishes. Allah said,</p><p>أَنزَلَ مِنَ الْسَّمَآءِ مَآءً</p><p>(He sends down water from the sky,) He sends rain,</p><p>فَسَالَتْ أَوْدِيَةٌ بِقَدَرِهَا</p><p>(and the valleys flow according to their measure,) each valley taking its share according to its capacity, for some valleys are wider and can retain more water than others which are small and thus retain smaller measures of water. This Ayah indicates that hearts differ, for some of them can retain substantial knowledge while others cannot entertain knowledge, but rather are bothered by knowledge,</p><p>فَاحْتَمَلَ السَّيْلُ زَبَدًا رَّابِيًا</p><p>(but the flood bears away the foam that mounts up to the surface) of the water that ran down the valleys; this is the first parable. Allah said next,</p><p>وَمِمَّا يُوقِدُونَ عَلَيْهِ فِى النَّارِ ابْتِغَآءَ حِلْيَةٍ أَوْ مَتَـعٍ</p><p>(and (also) from that (ore) which they heat in the fire in order to make ornaments or utensils...) This is the second parable, whereas gold and silver ore is heated with fire to make adornments with it, and iron and copper ore are heated to make pots and the like with it. Foam also rises to the …

He sendeth down water from the sky, so that valleys flow according to their measure, and the flood beareth (on its surface) swelling foam - from that which they smelt in the fire in order to make ornaments and tools riseth a foam like unto it - thus Allah coineth (the similitude of) the true and the false. Then, as for the foam, it passeth away as scum upon the banks, while, as for that which is of use to mankind, it remaineth in the earth. Thus Allah coineth the similitudes.

He sends down water from the skies, and the channels flow, each according to its measure: But the torrent bears away to foam that mounts up to the surface. Even so, from that (ore) which they heat in the fire, to make ornaments or utensils therewith, there is a scum likewise. Thus doth Allah (by parables) show forth Truth and Vanity. For the scum disappears like forth cast out; while that which is for the good of mankind remains on the earth. Thus doth Allah set forth parables.

He sends down water (rain) from the sky, and the valleys flow according to their measure, but the flood bears away the foam that mounts up to the surface, and (also) from that (ore) which they heat in the fire in order to make ornaments or utensils, rises a foam like unto it, thus does Allah (by parables) show forth truth and falsehood. Then, as for the foam it passes away as scum upon the banks, while that which is for the good of mankind remains in the earth. Thus Allah sets forth parables (for the truth and falsehood, i.e. Belief and disbelief).

He 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.
