Sahih al-Bukhari 6442
Narrated `Abdullah:
The Prophet (ﷺ) said, "Who among you considers the wealth of his heirs dearer to him than his own 
wealth?" They replied, "O Allah's Messenger (ﷺ)! There is none among us but loves his own wealth more." 
The Prophet (ﷺ) said, "So his wealth is whatever he spends (in Allah's Cause) during his life (on good 
deeds) while the wealth of his heirs is whatever he leaves after his death."
حَدَّثَنِي عُمَرُ بْنُ حَفْصٍ، حَدَّثَنِي أَبِي، حَدَّثَنَا الأَعْمَشُ، قَالَ حَدَّثَنِي إِبْرَاهِيمُ التَّيْمِيُّ، عَنِ الْحَارِثِ بْنِ سُوَيْدٍ، قَالَ عَبْدُ اللَّهِ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ أَيُّكُمْ مَالُ وَارِثِهِ أَحَبُّ إِلَيْهِ مِنْ مَالِهِ ‏"‏‏.‏ قَالُوا يَا رَسُولَ اللَّهِ مَا مِنَّا أَحَدٌ إِلاَّ مَالُهُ أَحَبُّ إِلَيْهِ‏.‏ قَالَ ‏"‏ فَإِنَّ مَالَهُ مَا قَدَّمَ، وَمَالُ وَارِثِهِ مَا أَخَّرَ ‏"‏‏.‏
