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.
The verse uses two apt parables. In the first parable, Truth (al Haqq) ,(is compared to water, and falsehood (al-Bâtil to) foam. Falsehood appears at first to prevail over the Truth like foam over water, but in the end, it is swept away by the waters powerful current. In the second parable, Truth is likened to a metal, which when melted to make ornaments, utensils, and tools, throws off the dross leaving behind the unmixed metal that is pure and bright. The parables
also signify that those who believe and work for the good of others and for the benefits of the people shall be granted long life. On the other hand, those who uphold evil practices and worthless customs
will be swept away before the mighty current of the true teachings.
