Sahih Muslim , Book 12, Hadith 152 (In-Book) ⓘ
Anas reported Allah's Messenger as saying: If the son of Adam were to possess two valleys of riches. he would long for the third one. And the stomach of the son of Adam is not filled but with dust. And Allah returns to him who repents.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَسَعِيدُ بْنُ مَنْصُورٍ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ يَحْيَى أَخْبَرَنَا وَقَالَ الآخَرَانِ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لَوْ كَانَ لاِبْنِ آدَمَ وَادِيَانِ مِنْ مَالٍ لاَبْتَغَى وَادِيًا ثَالِثًا وَلاَ يَمْلأُ جَوْفَ ابْنِ آدَمَ إِلاَّ التُّرَابُ وَيَتُوبُ اللَّهُ عَلَى مَنْ تَابَ " .
