Bulugh al-Maram, Book 11, Hadith 1316 (In-Book) ⓘ

’Umar (RAA) narrated, ‘The wealth of Banu an-Nadir (one of the Jewish tribes) was part of what Allah bestowed on His Messenger, and which the Muslims had not ridden on horses or camels to get (i.e. they did not have to fight); so they belonged specially to the Prophet who would give his family their sustenance for a year, then applied what remained for horses and weapons and equipment in the Path of Allah, Who is Great and Glorious.” Agreed upon.

وَعَنْهُ قَالَ: { كَانَتْ أَمْوَالُ بَنِي اَلنَّضِيرِ مِمَّا أَفَاءَ اَللَّهُ عَلَى رَسُولِهِ, مِمَّا لَمْ يُوجِفْ عَلَيْهِ اَلْمُسْلِمُونَ بِخَيْلٍ وَلَا رِكَابٍ, فَكَانَتْ لِلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-خَاصَّةً, فَكَانَ يُنْفِقُ عَلَى أَهْلِهِ نَفَقَةَ سَنَةٍ, وَمَا بَقِيَ يَجْعَلُهُ فِي اَلْكُرَاعِ وَالسِّلَاحِ, عُدَّةً فِي سَبِيلِ اَللَّهِ" } مُتَّفَقٌ عَلَيْهِ.‏ 1‏.‏ ‏1 ‏- صحيح.‏ رواه البخاري ( 2904 )‏، ومسلم ( 1757 )‏ ( 48 )‏.‏ "يوجف": الإيجاف هو الإسراع، والمراد أنه حصل بلا قتال.‏ "الكراع" الدواب التي تصلح للحرب.‏
