The Book of Zuhd and Softening of Hearts
Ṣaḥīḥ Muslim 7422
يَقُولُ الْعَبْدُ مَالِي مَالِي إِنَّمَا لَهُ مِنْ مَالِهِ ثَلاَثٌ مَا أَكَلَ فَأَفْنَى أَوْ لَبِسَ فَأَبْلَى أَوْ أَعْطَى فَاقْتَنَى وَمَا سِوَى ذَلِكَ فَهُوَ ذَاهِبٌ وَتَارِكُهُ لِلنَّاسِ
yaqūlu al-ʿabdu mālī mālī innamā lah min mālihi thalāthun mā akala fa-afnā aw labisa fa-ablā aw aʿṭā fāqtanā wamā siwā dhalika fahuwa dhāhibun watārikuhu lilnnāsi

The full narration
Abu Huraira reported Allah's Messenger (ﷺ) as saying:A servant says, My wealth. my wealth, but out of his wealth three things are only his: whatever he eats and makes use of or by means of which he dresses himself and it wears out or he gives as charity, and this is what he stored for himself (as a reward for the Hereafter), and what is beyond this (it is of no use to you) because you are to depart and leave it for other people
