Sunan Abi Dawud, 2970
sahih· Al-Albani

Narrating the above tradition, 'Aishah added:

Abu Bakr refused that to her. Her said: I am not going to leave anything the Messenger of Allah (ﷺ) used to do but I shall carry it out. I fear if I depart a little from his practice, I shall diverge (from the right path). As regards his sadaqah (property) at Medina, 'Umar had given it to 'Ali ad 'Abbas (Allah be pleased with them), and 'Ali dominated it. As for Khaibar and Fadak, 'Umar retained them. He said: They were the sadaqah (property) of the Messenger of Allah (ﷺ), exclusively reserved for his purposes that happened, and for his emergent needs. Their management was assigned to the one who was in authority. He said: They are in that condition to the present day.

حَدَّثَنَا حَجَّاجُ بْنُ أَبِي يَعْقُوبَ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ بْنِ سَعْدٍ، حَدَّثَنَا أَبِي، عَنْ صَالِحٍ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي عُرْوَةُ، أَنَّ عَائِشَةَ، رضى الله عنها أَخْبَرَتْهُ بِهَذَا الْحَدِيثِ، قَالَ فِيهِ فَأَبَى أَبُو بَكْرٍ رضى الله عنه عَلَيْهَا ذَلِكَ وَقَالَ لَسْتُ تَارِكًا شَيْئًا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَعْمَلُ بِهِ إِلاَّ عَمِلْتُ بِهِ إِنِّي أَخْشَى إِنْ تَرَكْتُ شَيْئًا مِنْ أَمْرِهِ أَنْ أَزِيغَ فَأَمَّا صَدَقَتُهُ بِالْمَدِينَةِ فَدَفَعَهَا عُمَرُ إِلَى عَلِيٍّ وَعَبَّاسٍ رضى الله عنهم فَغَلَبَهُ عَلِيٌّ عَلَيْهَا وَأَمَّا خَيْبَرُ وَفَدَكُ فَأَمْسَكَهُمَا عُمَرُ وَقَالَ هُمَا صَدَقَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم كَانَتَا لِحُقُوقِهِ الَّتِي تَعْرُوهُ وَنَوَائِبِهِ وَأَمْرُهُمَا إِلَى مَنْ وَلِيَ الأَمْرَ ‏.‏ قَالَ فَهُمَا عَلَى ذَلِكَ إِلَى الْيَوْمِ ‏.‏
