صَحِيحُ الْبُخَارِيِّ
Sahih al-Bukhari 3154
One-fifth of Booty to the Cause of Allah (Khumus)
The food gained as war booty in the battlefield
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ كُنَّا نُصِيبُ فِي مَغَازِينَا الْعَسَلَ وَالْعِنَبَ فَنَأْكُلُهُ وَلاَ نَرْفَعُهُ.
Narrated Ibn `Umar: In our holy battles, we used to get honey and grapes, as war booty which we would eat and would not store.
