Sunan an-Nasa'i, Book 30, Hadith 3 (In-Book) ⓘ
It was narrated from Mutarrif, from his father, that the Prophet said: "The mutual rivalry (for piling up of worldly things) diverts you, 'Until you visit the graves (i.e. till you die).' The son of Adam says: 'My wealth, my wealth,' but your wealth is what you eat and consume, or what you wear and it wears out, or what you give in charity and send on ahead (for the Hereafter).'"
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ مُطَرِّفٍ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " {أَلْهَاكُمُ التَّكَاثُرُ * حَتَّى زُرْتُمُ الْمَقَابِرَ} قَالَ يَقُولُ ابْنُ آدَمَ مَالِي مَالِي وَإِنَّمَا مَالُكَ مَا أَكَلْتَ فَأَفْنَيْتَ أَوْ لَبِسْتَ فَأَبْلَيْتَ أَوْ تَصَدَّقْتَ فَأَمْضَيْتَ ".
