Malik ibn Aws al-Hadthan said: One of the arguments put forward by Umar was that he said that the Messenger of Allah ﷺ received three things exclusively to himself: Banu an-Nadir, Khaybar and Fadak. The Banu an-Nadir property was kept wholly for his emergent needs, Fadak for travellers, and Khaybar was divided by the Messenger of Allah ﷺ into three sections: two for Muslims, and one as a contribution for his family. If anything remained after making the contribution of his family, he divided it among the poor Emigrants.  

كَانَ فِيمَا احْتَجَّ بِهِ عُمَرُ ؓ أَنَّهُ قَالَ كَانَتْ لِرَسُولِ اللَّهِ ﷺ ثَلاَثُ صَفَايَا بَنُو النَّضِيرِ وَخَيْبَرُ وَفَدَكُ فَأَمَّا بَنُو النَّضِيرِ فَكَانَتْ حُبْسًا لِنَوَائِبِهِ وَأَمَّا فَدَكُ فَكَانَتْ حُبْسًا لأَبْنَاءِ السَّبِيلِ وَأَمَّا خَيْبَرُ فَجَزَّأَهَا رَسُولُ اللَّهِ ﷺ ثَلاَثَةَ أَجْزَاءٍ جُزْءَيْنِ بَيْنَ الْمُسْلِمِينَ وَجُزْءًا نَفَقَةً لأَهْلِهِ فَمَا فَضَلَ عَنْ نَفَقَةِ أَهْلِهِ جَعَلَهُ بَيْنَ فُقَرَاءِ الْمُهَاجِرِينَ  

"عَنْ عُمَرَ قال: كَانَتْ لرَسُولِ الله ﷺ ثَلَاثُ صَفَايَا: بَنُو النَّضِيرِ فَكَانَتْ حُبْسًا لِنَوَائِبِهِ، وَأَمَّا فَدَكُ فَكَانَتْ حُبْسًا لأَبْنَاءِ السَّبِيلِ، وَأَمَّا خَيْبَرُ فَجزَّأَهَا رَسُولُ الله ﷺ ثَلَاثَةَ أَجْزَاءٍ: جُزْأَيْنِ بَيْنِ الْمُسْلِمِينَ، وَجُزْءًا لِنَفَقَتِهِ وَنَفَقَةِ أَهْلِهِ، فَمَا فَضَل عَن نَفَقَةِ أَهْلِهِ جَعَلَهُ بَيْنَ الفُقَرَاءِ وَالمَسَاكِين".
