Narrated 'Umar:The properties of Banu al-Nadir were part of what Allah bestowed on His Apostle from what the Muslims has not ridden on horses or camels to get; so they belonged specially to the Messenger of Allah (ﷺ) who gave his family their annual contribution.Ibn 'Abdah said: His family (ahlihi) and not the members of his houses (ahl baitihi) ; then applied what remained for horses and weapons in Allah's path.
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَأَحْمَدُ بْنُ عَبْدَةَ، - الْمَعْنَى - أَنَّ سُفْيَانَ بْنَ عُيَيْنَةَ، أَخْبَرَهُمْ عَنْ عَمْرِو بْنِ دِينَارٍ، عَنِ الزُّهْرِيِّ، عَنْ مَالِكِ بْنِ أَوْسِ بْنِ الْحَدَثَانِ، عَنْ عُمَرَ، قَالَ كَانَتْ أَمْوَالُ بَنِي النَّضِيرِ مِمَّا أَفَاءَ اللَّهُ عَلَى رَسُولِهِ مِمَّا لَمْ يُوجِفِ الْمُسْلِمُونَ عَلَيْهِ بِخَيْلٍ وَلاَ رِكَابٍ كَانَتْ لِرَسُولِ اللَّهِ صلى الله عليه وسلم خَالِصًا يُنْفِقُ عَلَى أَهْلِ بَيْتِهِ - قَالَ ابْنُ عَبْدَةَ يُنْفِقُ عَلَى أَهْلِهِ قُوتَ سَنَةٍ - فَمَا بَقِيَ جُعِلَ فِي الْكُرَاعِ وَعُدَّةً فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ قَالَ ابْنُ عَبْدَةَ فِي الْكُرَاعِ وَالسِّلاَحِ .
