Surah Ar-Ra'd, Verse 17

أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءٗ فَسَالَتۡ أَوۡدِيَةُۢ بِقَدَرِهَا فَٱحۡتَمَلَ ٱلسَّيۡلُ زَبَدٗا رَّابِيٗاۖ وَمِمَّا يُوقِدُونَ عَلَيۡهِ فِي ٱلنَّارِ ٱبۡتِغَآءَ حِلۡيَةٍ أَوۡ مَتَٰعٖ زَبَدٞ مِّثۡلُهُۥۚ كَذَٰلِكَ يَضۡرِبُ ٱللَّهُ ٱلۡحَقَّ وَٱلۡبَٰطِلَۚ فَأَمَّا ٱلزَّبَدُ فَيَذۡهَبُ جُفَآءٗۖ وَأَمَّا مَا يَنفَعُ ٱلنَّاسَ فَيَمۡكُثُ فِي ٱلۡأَرۡضِۚ كَذَٰلِكَ يَضۡرِبُ ٱللَّهُ ٱلۡأَمۡثَالَ١٧

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.
