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. (Using translation from Abū Dāʾūd 2734)  

أَتَيْنَا رَسُولَ اللهِ ﷺ وَنَحْنُ أَرْبَعَةُ نَفَرٍ وَمَعَنَا فَرَسٌ فَأَعْطَى كُلَّ إِنْسَانٍ مِنَّا سَهْمًا وَأَعْطَى الْفَرَسَ سَهْمَيْنِ
