The temporary nature of worldly possessions

كِلْتَا ٱلْجَنَّتَيْنِ ءَاتَتْ أُكُلَهَا وَلَمْ تَظْلِم مِّنْهُ شَيْـًٔا ۚ وَفَجَّرْنَا خِلَـٰلَهُمَا نَهَرًا

Each of the two gardens produced its fruit and did not fall short thereof in anything. And We caused to gush forth within them a river.

مَآ أَغْنَىٰ عَنْهُ مَالُهُۥ وَمَا كَسَبَ

His wealth will not avail him or that which he gained.
