Ibn ‘Umar said “The Apostle of Allaah ﷺ allotted three portions for a man and his horse, one for him and two for his horse.  

أَنَّ رَسُولَ اللَّهِ ﷺ أَسْهَمَ لِرَجُلٍ وَلِفَرَسِهِ ثَلاَثَةَ أَسْهُمٍ سَهْمًا لَهُ وَسَهْمَيْنِ لِفَرَسِهِ  

We four persons, came to the Messenger of Allah ﷺ, and we (i.e. each one of us) had horses. He therefore, allotted one portion for each of us, and two portions for his horse.  

أَتَيْنَا رَسُولَ اللَّهِ ﷺ أَرْبَعَةَ نَفَرٍ وَمَعَنَا فَرَسٌ فَأَعْطَى كُلَّ إِنْسَانٍ مِنَّا سَهْمًا وَأَعْطَى لِلْفَرَسِ سَهْمَيْنِ  

The tradition mentioned above has also been transmitted by Abu ‘Umrah through a different chain of narrators to the same effect. But this version has “Three Persons” and added “To the horseman three portions.”  

أَنَّهُ قَالَ ثَلاَثَةَ نَفَرٍ زَادَ فَكَانَ لِلْفَارِسِ ثَلاَثَةُ أَسْهُمٍ
