حَدَّثَنَا حَسَنٌ حَدَّثَنَا ابْنُ لَهِيعَةَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ أَبِي جَعْفَرٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ رَأَيْتُ الْمَغَانِمَ تُجَزَّأُ خَمْسَةَ أَجْزَاءٍ ثُمَّ يُسْهَمُ عَلَيْهَا فَمَا كَانَ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَهُوَ لَهُ يَتَخَيَّرُ
مسند امام احمد بن حنبل · Hadith 5397
It was narrated that Ibn 'Umar said: I saw the booty being divided into five equal parts, that lots were drawn, and whatever was allocated to the Messenger of Allah (PBUH) (as a result of drawing lots) was his, and he would choose (what to do with it).
