Sahih al-Bukhari 5668
Narrated Sa`d:
Allah's Messenger (ﷺ) came to visit me during my ailment which had been aggravated during Hajjat-al- 
Wada`. I said to him, "You see how sick I am. I have much property but have no heir except my only 
daughter May I give two thirds of my property in charity?"! He said, "No." I said, "Half of it?" He 
said, "No." I said "One third?" He said, "One third is too much, for to leave your heirs rich is better 
than to leave them poor, begging of others. Nothing you spend seeking Allah's pleasure but you shall 
get a reward for it, even for what you put in the mouth of your wife."
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ بْنِ أَبِي سَلَمَةَ، أَخْبَرَنَا الزُّهْرِيُّ، عَنْ عَامِرِ بْنِ سَعْدٍ، عَنْ أَبِيهِ، قَالَ جَاءَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم يَعُودُنِي مِنْ وَجَعٍ اشْتَدَّ بِي زَمَنَ حَجَّةِ الْوَدَاعِ فَقُلْتُ بَلَغَ بِي مَا تَرَى وَأَنَا ذُو مَالٍ وَلاَ يَرِثُنِي إِلاَّ ابْنَةٌ لِي أَفَأَتَصَدَّقُ بِثُلُثَىْ مَالِي قَالَ ‏"‏ لاَ ‏"‏‏.‏ قُلْتُ بِالشَّطْرِ قَالَ ‏"‏ لاَ ‏"‏‏.‏ قُلْتُ الثُّلُثُ قَالَ ‏"‏ الثُّلُثُ كَثِيرٌ، أَنْ تَدَعَ وَرَثَتَكَ أَغْنِيَاءَ خَيْرٌ مِنْ أَنْ تَذَرَهُمْ عَالَةً يَتَكَفَّفُونَ النَّاسَ وَلَنْ تُنْفِقَ نَفَقَةً تَبْتَغِي بِهَا وَجْهَ اللَّهِ إِلاَّ أُجِرْتَ عَلَيْهَا حَتَّى مَا تَجْعَلُ فِي فِي امْرَأَتِكَ ‏"‏‏.‏
