Ar-Ra’d 13:17 انزل من السماء ماء فسالت اودية بقدرها فاحتمل السيل زبدا رابيا ومما يوقدون عليه في النار ابتغاء حلية او متاع زبد مثله كذالك يضرب الله الحق والباطل فاما الزبد فيذهب جفاء واما ما ينفع الناس فيمكث في الارض كذالك يضرب الله الامثال ١٧

He sends down rain from the sky, causing the valleys to flow, each according to its capacity. The currents then carry along rising foam, similar to the slag produced from metal that people melt in the fire for ornaments or tools. This is how Allah compares truth to falsehood. The ˹worthless˺ scum is then cast away, but what benefits people remains on the earth. This is how Allah sets forth parables.

He sends down from the sky, rain, and valleys flow according to their capacity, and the torrent carries a rising foam. And from that [ore] which they heat in the fire, desiring adornments and utensils, is a foam like it. Thus Allāh presents [the example of] truth and falsehood. As for the foam, it vanishes, [being] cast off; but as for that which benefits the people, it remains on the earth. Thus does Allāh present examples.
