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 used to give to some of the detachments he sent out booty for themselves in particular apart from the division made to the whole army. (Bukhari and Muslim.)
