Jami` at-Tirmidhi, Book 21, Hadith 14 (In-Book) ⓘ
It has been related by Az-Zuhri, that the Prophet gave a portion to some people among the Jews who fought along with him. This was narrated to us by Qutaibah (who said): "Abdul-Warith bin Sa'eed narrated to us from 'Urwah bin Thabit, from Az-Zuhri." This Hadith is Hasan Gharib.
وَيُرْوَى عَنِ الزُّهْرِيِّ، أَنَّ النَّبِيَّ صلى الله عليه وسلم أَسْهَمَ لِقَوْمٍ مِنَ الْيَهُودِ قَاتَلُوا مَعَهُ . حَدَّثَنَا بِذَلِكَ قُتَيْبَةُ بْنُ سَعِيدٍ أَخْبَرَنَا عَبْدُ الْوَارِثِ بْنُ سَعِيدٍ عَنْ عَزْرَةَ بْنِ ثَابِتٍ عَنِ الزُّهْرِيِّ بِهَذَا . هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ .
