Hadith 337

(حديث مرفوع) حَدَّثَنَا سُفْيَانُ ، عَنْ عَمْرٍو ، عَنِ الزُّهْرِيِّ ، عَنْ مَالِكِ بْنِ أَوْسٍ ، قَالَ : أَرْسَلَ إِلَيَّ عُمَرُ . . . فَذَكَرَ الْحَدِيثَ ، وَقَالَ : " إِنَّ أَمْوَالَ بَنِي النَّضِيرِ كَانَتْ مِمَّا أَفَاءَ اللَّهُ عَلَى رَسُولِهِ ، مِمَّا لَمْ يُوجِفْ عَلَيْهِ الْمُسْلِمُونَ بِخَيْلٍ وَلَا رِكَابٍ ، فَكَانَ يُنْفِقُ عَلَى أَهْلِهِ مِنْهَا نَفَقَةَ سَنَةٍ ، وَمَا بَقِيَ جَعَلَهُ فِي الْكُرَاعِ وَالسِّلَاحِ عُدَّةً فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ " .
It is narrated from Sayyiduna Umar (may Allah be pleased with him) that the wealth obtained from Banu Nadir was from the category of Fay’ (spoils of war without fighting), which Allah granted to His Prophet, and the Muslims did not have to ride horses or any other mounts for it. Therefore, this wealth was exclusively for the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) would give his pure wives their yearly maintenance from it at one time, and whatever remained, he would use to provide horses and other weapons (that could be used in jihad).
