وَآخُذُ اللَّفْظَ فِضَّةً فَإِذَا مَا صُغْتُهُ قِيلَ إِنَّهُ ذَهَبُ
I take a word like silver; when I shape it, people call it gold.
Al-fiḍḍah / al-dhahab are significant not as a rhyme pair but as silver and gold. The speaker compares literary composition to refining precious material: ordinary words become a more valued form through artistry.
This is a necessary control example. Not every polished phrase is best explained by sajʿ or jinās. Here the central device is transformation imagery, with the verb of shaping as its pivot. The boast about craftsmanship does not independently establish that the market rewards that craft.
