عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى قَالَ سَمِعْتُ أَمِيرَ الْمُؤْمِنِينَ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ يَقُولُ اجْتَمَعْتُ أَنَا وَفَاطِمَةُ وَالْعَبَّاسُ وَزَيْدُ بْنُ حَارِثَةَ رَضِيَ اللَّهُ عَنْهُمْ عِنْدَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ الْعَبَّاسُ يَا رَسُولَ اللَّهِ كَبِرَ سِنِّي وَرَقَّ عَظْمِي وَكَثُرَتْ مُؤْنَتِي فَإِنْ رَأَيْتَ يَا رَسُولَ اللَّهِ أَنْ تَأْمُرَ لِي بِكَذَا وَكَذَا وَسْقًا مِنْ طَعَامٍ فَافْعَلْ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَفْعَلُ ذَلِكَ ثُمَّ قَالَ زَيْدُ بْنُ حَارِثَةَ يَا رَسُولَ اللَّهِ كُنْتَ أَعْطَيْتَنِي أَرْضًا كَانَتْ مَعِيشَتِي مِنْهَا ثُمَّ قَبَضْتَهَا فَإِنْ رَأَيْتَ أَنْ تَرُدَّهَا عَلَيَّ فَافْعَلْ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَفْعَلُ ذَلِكَ قَالَ فَقُلْتُ أَنَا يَا رَسُولَ اللَّهِ إِنْ رَأَيْتَ أَنْ تُوَلِّيَنِي هَذَا الْحَقَّ الَّذِي جَعَلَهُ اللَّهُ لَنَا فِي كِتَابِهِ مِنْ هَذَا الْخُمُسِ فَأَقْسِمُهُ فِي حَيَاتِكَ كَيْ لَا يُنَازِعَنِيهِ أَحَدٌ بَعْدَكَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَفْعَلُ ذَلِكَ فَوَلَّانِيهِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَسَمْتُهُ فِي حَيَاتِهِ ثُمَّ وَلَّانِيهِ أَبُو بَكْرٍ فَقَسَمْتُهُ فِي حَيَاتِهِ ثُمَّ وَلَّانِيهِ عُمَرُ فَقَسَمْتُهُ فِي حَيَاتِهِ حَتَّى كَانَتْ آخِرُ سَنَةٍ مِنْ سِنِي عُمَرَ فَإِنَّهُ أَتَاهُ مَالٌ كَثِيرٌ {وَاعْلَمُوا أَنَّمَا غَنِمْتُمْ مِنْ شَيْءٍ فَأَنَّ لِلَّهِ خُمُسَهُ وَلِلرَّسُولِ وَلِذِي الْقُرْبَى} [الأنفال: 41]
It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: I, Sayyida Fatima, Sayyiduna Abbas, and Sayyiduna Zaid bin Haritha (may Allah be pleased with them), gathered in the presence of the Messenger of Allah. Sayyiduna Abbas (may Allah be pleased with him) said: O Messenger of Allah! Now I have grown old, my bones have become weak, and I have endured much hardship, so if you deem it appropriate, please order for me a certain amount of grain. The Prophet (peace and blessings be upon him) said: We will do so. Then Sayyiduna Zaid bin Haritha (may Allah be pleased with him) said: O Messenger of Allah! You had given me a piece of land, which was my means of livelihood, but then you took it back; if you deem it appropriate, please give it to me again. The Prophet (peace and blessings be upon him) said: We will do so. Then I said: O Messenger of Allah! If you deem it appropriate, appoint me as the guardian of that right which Allah Almighty has mentioned in His Book in the form of khumus, so that I may distribute it during your lifetime, so that after you no one may dispute with me about it. The Prophet (peace and blessings be upon him) said: We will do so. Thus, the Prophet (peace and blessings be upon him) appointed me as its guardian, and I distributed it during his blessed life. Then Sayyiduna Abu Bakr (may Allah be pleased with him) appointed me as its guardian, and I distributed it during his lifetime as well. Then Sayyiduna Umar (may Allah be pleased with him) appointed me as its guardian, and I distributed it during his lifetime, until it was the last year of Sayyiduna Umar (may Allah be pleased with him) and a great amount of wealth came to him.
