Sahih Bukhari Volume 5, Book 64, Hadith 4036

قَالَ فَحَدَّثْتُ هَذَا الْحَدِيثَ، عُرْوَةَ بْنَ الزُّبَيْرِ فَقَالَ صَدَقَ مَالِكُ بْنُ أَوْسٍ، أَنَا سَمِعْتُ عَائِشَةَ ـ رضى الله عنها ـ زَوْجَ النَّبِيِّ صلى الله عليه وسلم تَقُولُ أَرْسَلَ أَزْوَاجُ النَّبِيِّ صلى الله عليه وسلم عُثْمَانَ إِلَى أَبِي بَكْرٍ يَسْأَلْنَهُ ثُمُنَهُنَّ مِمَّا أَفَاءَ اللَّهُ عَلَى رَسُولِهِ صلى الله عليه وسلم، فَكُنْتُ أَنَا أَرُدُّهُنَّ، فَقُلْتُ لَهُنَّ أَلاَ تَتَّقِينَ اللَّهَ، أَلَمْ تَعْلَمْنَ أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَقُولُ ‏"‏ لاَ نُورَثُ، مَا تَرَكْنَا صَدَقَةٌ ـ يُرِيدُ بِذَلِكَ نَفْسَهُ ـ إِنَّمَا يَأْكُلُ آلُ مُحَمَّدٍ صلى الله عليه وسلم فِي هَذَا الْمَالِ ‏"‏‏.‏ فَانْتَهَى أَزْوَاجُ النَّبِيِّ صلى الله عليه وسلم إِلَى مَا أَخْبَرَتْهُنَّ‏.‏ قَالَ فَكَانَتْ هَذِهِ الصَّدَقَةُ بِيَدِ عَلِيٍّ، مَنَعَهَا عَلِيٌّ عَبَّاسًا فَغَلَبَهُ عَلَيْهَا، ثُمَّ كَانَ بِيَدِ حَسَنِ بْنِ عَلِيٍّ، ثُمَّ بِيَدِ حُسَيْنِ بْنِ عَلِيٍّ، ثُمَّ بِيَدِ عَلِيِّ بْنِ حُسَيْنٍ وَحَسَنِ بْنِ حَسَنٍ، كِلاَهُمَا كَانَا يَتَدَاوَلاَنِهَا، ثُمَّ بِيَدِ زَيْدِ بْنِ حَسَنٍ، وَهْىَ صَدَقَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم حَقًّا

The sub-narrator said, "I told 'Urwa bin Az-Zubair of this Hadith and he said, 'Malik bin Aus has told the truth" I heard 'Aisha, the wife of the Prophet saying, 'The wives of the Prophet sent 'Uthman to Abu Bakr demanding from him their 1/8 of the Fai which Allah had granted to his Apostle. But I used to oppose them and say to them: Will you not fear Allah? Don't you know that the Prophet used to say: Our property is not inherited, but whatever we leave is to be given in charity? The Prophet mentioned that regarding himself. He added: 'The family of Muhammad can take their sustenance from this property. So the wives of the Prophet stopped demanding it when I told them of that.' So, this property (of Sadaqa) was in the hands of Ali who withheld it from 'Abbas and overpowered him. Then it came in the hands of Hasan bin 'Ali, then in the hands of Husain bin 'Ali, and then in the hands of Ali bin Husain and Hasan bin Hasan, and each of the last two used to manage it in turn, then it came in the hands of Zaid bin Hasan, and it was truly the Sadaqa of Allah's Apostle."
