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»
Abu Huraira reported God’s Messenger as saying, "Spoils were not lawful for anyone before us, that being because God saw our weakness and incapacity and made them allowable for us.” (Bukhari and Muslim.)
