Narrated Anas bin Malik:

Allah's Apostle ﷺ said, "If Adam's son had a valley full of gold, he would like to have two valleys, for nothing fills his mouth except dust. And Allah forgives him who repents to Him."

وَقَالَ لَنَا أَبُو الْوَلِيدِ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، عَنْ أُبَىٍّ، قَالَ كُنَّا نَرَى هَذَا مِنَ الْقُرْآنِ حَتَّى نَزَلَتْ {أَلْهَاكُمُ التَّكَاثُرُ}
