عَنْ أَبِي هُرَيْرَةَ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «فَلَمْ تَحِلَّ الْغَنَائِمُ لِأَحَدٍ مِنْ قَبْلِنَا ذَلِكَ بِأَنَّ اللَّهَ رَأَى ضعفنا وعجزنا فطيها لنا»

Ibn ‘Umar told that God’s Messenger allotted three portions for a man and his horse, one for him and two for his horse. (Bukhari and Muslim.)
