Hoarding Wealth - Obsession in Humans

 You're actually right. Allah has mentioned this psychology/obsession in the Qur'an in Surah Al-Imran:

زُيِّنَ لِلنَّاسِ حُبُّ ٱلشَّهَوَٰتِ مِنَ ٱلنِّسَآءِ وَٱلْبَنِينَ وَٱلْقَنَـٰطِيرِ ٱلْمُقَنطَرَةِ مِنَ ٱلذَّهَبِ وَٱلْفِضَّةِ وَٱلْخَيْلِ ٱلْمُسَوَّمَةِ وَٱلْأَنْعَـٰمِ وَٱلْحَرْثِ ۗ ذَٰلِكَ مَتَـٰعُ ٱلْحَيَوٰةِ ٱلدُّنْيَا ۖ وَٱللَّهُ عِندَهُۥ حُسْنُ ٱلْمَـَٔابِ ١٤

"Beautified for people is the love of that which they desire - of women and sons, heaped-up sums of gold and silver, fine branded horses, and cattle and tilled land. That is the enjoyment of worldly life, but Allah has with Him the best return."

[Quran 3:14]

The word وَٱلْقَنَـٰطِيرِ ٱلْمُقَنطَرَةِ has been translated as:

- Heaps of Stored Up [gold, silver]

- Hoarded Treasures

- accumulated piles
