It was narrated from Ibn ‘Umar that the Prophet ﷺ 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. (Using translation from Ibn Mājah 2854)   

«أَنَّ رَسُولَ اللَّهِ ﷺ أَسْهَمَ يَوْمَ خَيْبَرَ لِلْفَارِسِ ثَلَاثَةَ أَسْهُمٍ وَلِلرَّاجِلِ سَهْمًا»  

[Machine] From the son of Umar, similar to him.  

عَنْ ابْنِ عُمَرَ نَحْوَهُ
