Sahih Bukhari Volume 2, Book 23, Hadith 1296

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عَامِرِ بْنِ سَعْدِ بْنِ أَبِي وَقَّاصٍ، عَنْ أَبِيهِ ـ رضى الله عنه ـ قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَعُودُنِي عَامَ حَجَّةِ الْوَدَاعِ مِنْ وَجَعٍ اشْتَدَّ بِي فَقُلْتُ إِنِّي قَدْ بَلَغَ بِي مِنَ الْوَجَعِ وَأَنَا ذُو مَالٍ، وَلاَ يَرِثُنِي إِلاَّ ابْنَةٌ، أَفَأَتَصَدَّقُ بِثُلُثَىْ مَالِي قَالَ ‏"‏ لاَ ‏"‏‏.‏ فَقُلْتُ بِالشَّطْرِ فَقَالَ ‏"‏ لاَ ‏"‏ ثُمَّ قَالَ ‏"‏ الثُّلُثُ وَالثُّلْثُ كَبِيرٌ ـ أَوْ كَثِيرٌ ـ إِنَّكَ أَنْ تَذَرَ وَرَثَتَكَ أَغْنِيَاءَ خَيْرٌ مِنْ أَنْ تَذَرَهُمْ عَالَةً يَتَكَفَّفُونَ النَّاسَ، وَإِنَّكَ لَنْ تُنْفِقَ نَفَقَةً تَبْتَغِي بِهَا وَجْهَ اللَّهِ إِلاَّ أُجِرْتَ بِهَا، حَتَّى مَا تَجْعَلُ فِي فِي امْرَأَتِكَ ‏"‏‏.‏ فَقُلْتُ يَا رَسُولَ اللَّهِ، أُخَلَّفُ بَعْدَ أَصْحَابِي قَالَ ‏"‏ إِنَّكَ لَنْ تُخَلَّفَ فَتَعْمَلَ عَمَلاً صَالِحًا إِلاَّ ازْدَدْتَ بِهِ دَرَجَةً وَرِفْعَةً، ثُمَّ لَعَلَّكَ أَنْ تُخَلَّفَ حَتَّى يَنْتَفِعَ بِكَ أَقْوَامٌ وَيُضَرَّ بِكَ آخَرُونَ، اللَّهُمَّ أَمْضِ لأَصْحَابِي هِجْرَتَهُمْ، وَلاَ تَرُدَّهُمْ عَلَى أَعْقَابِهِمْ، لَكِنِ الْبَائِسُ سَعْدُ ابْنُ خَوْلَةَ، يَرْثِي لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ مَاتَ بِمَكَّةَ ‏"

Narrated By 'Amir bin Sad bin Abi Waqqas : That his father said, "In the year of the last Hajj of the Prophet I became seriously ill and the Prophet used to visit me inquiring about my health. I told him, 'I am reduced to this state because of illness and I am wealthy and have no inheritors except a daughter, (In this narration the name of 'Amir bin Sad is mentioned and in fact it is a mistake; the narrator is 'Aisha bint Sad bin Abi Waqqas). Should I give two-thirds of my property in charity?' He said, 'No.' I asked, 'Half?' He said, 'No.' then he added, 'One-third, and even one-third is much. You'd better leave your inheritors wealthy rather than leaving them poor, begging others. You will get a reward for whatever you spend for Allah's sake, even for what you put in your wife's mouth.' I said, 'O Allah's Apostle! Will I be left alone after my companions have gone?' He said, 'If you are left behind, whatever good deeds you will do will up-grade you and raise you high. And perhaps you will have a long life so that some people will be benefited by you while others will be harmed by you. O Allah! Complete the emigration of my companions and do not turn them renegades.' But Allah's Apostle felt sorry for poor Sad bin Khaula as he died in Mecca." (but Sad bin Abi Waqqas lived long after the Prophet (p.b.u.h).)
