حَدَّثَنَا سُفْيَانُ عَنْ عَمْرٍو وَمَعْمَرٍ عَنِ الزُّهْرِيِّ عَنْ مَالِكِ بْنِ أَوْسِ بْنِ الْحَدَثَانِ عَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَتْ أَمْوَالُ بَنِي النَّضِيرِ مِمَّا أَفَاءَ اللَّهُ عَلَى رَسُولِهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِمَّا لَمْ يُوجِفْ الْمُسْلِمُونَ عَلَيْهِ بِخَيْلٍ وَلَا رِكَابٍ فَكَانَتْ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَالِصَةً وَكَانَ يُنْفِقُ عَلَى أَهْلِهِ مِنْهَا نَفَقَةَ سَنَةٍ وَقَالَ مَرَّةً قُوتَ سَنَةٍ وَمَا بَقِيَ جَعَلَهُ فِي الْكُرَاعِ وَالسِّلَاحِ عُدَّةً فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ
مسند امام احمد بن حنبل · Hadith 171
It was narrated that 'Umar bin al-Khattab (RA) said: The wealth of Banu an-Nadeer was among the fax that Allah bestowed upon His Messenger (PBUH), for which the Muslims made no expedition with either cavalry or camelry (cf. al-Hashr 59:6). It was only for the Messenger of Allah and he used to spend from it on his family's annual expenses - and on one occasion he said: his annual food supply - and what was left he spent on horses and weapons in preparation for jihad for the sake of Allah, may He be glorified and exalted.
