Sunan Ibn Majah, Hadith 2854 ⓘ
It was narrated from Ibn ‘Umar that the Prophet distributed the war spoils on the Day of Khaibar, giving three shares to the horseman, two shares for the horse, and one share for the man.
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم أَسْهَمَ يَوْمَ خَيْبَرَ لِلْفَارِسِ ثَلاَثَةَ أَسْهُمٍ لِلْفَرَسِ سَهْمَانِ وَلِلرَّجُلِ سَهْمٌ .
