It has been related by Az-Zuhri, that the Prophet (ﷺ) 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 ‏.‏
