Mishkat al-Masabih
Ibn ‘Umar said that in the time of God’s Messenger an army got food and honey in booty and a fifth was not taken from them. Abu Dawud transmitted it.
وَعَن ابنِ عُمَرَ: أَنَّ جَيْشًا غَنِمُوا فِي زَمَنِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ طَعَامًا وَعَسَلًا فَلَمْ يُؤخذْ منهمُ الْخمس. رَوَاهُ أَبُو دَاوُد
