"The mutual increase diverts you". He ﷺ said: "The son of Adam says:'My wealth, my wealth, but is there something for you from your wealth besides what you give in charity that remains, or you eat which perishes, or what you wear that grows worn?" (Using translation from Tirmidhī 2342)
أَنَّ رَجُلًا انْتَهَى إِلَى رَسُولِ اللهِ ﷺ وَهُوَ يَقُولُ وَقَالَ وَكِيعٌ مَرَّةً إِنَّهُ انْتَهَى إِلَى النَّبِيِّ ﷺ وَهُوَ يَقْرَأُ {أَلْهَاكُمُ التَّكَاثُرُ حَتَّى زُرْتُمُ الْمَقَابِرَ} [التكاثر 2] قَالَ يَقُولُ ابْنُ آدَمَ مَالِي مَالِي وَهَلْ لَكَ مِنْ مَالِكَ إِلَّا مَا تَصَدَّقْتَ فَأَمْضَيْتَ أَوْ لَبِسْتَ فَأَبْلَيْتَ أَوْ أَكَلْتَ فَأَفْنَيْتَ
