Narrated Nafi from Ibn Umar:

Allah's Apostle sent a Sariya towards Najd, and Abdullah bin 'Umar was in the Sariya. They gained a great number of camels as war booty. The share of each one of them was twelve or eleven camels, and they were given an extra camel each.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ سَرِيَّةً فِيهَا عَبْدُ اللَّهِ قِبَلَ نَجْدٍ، فَغَنِمُوا إِبِلاً كَثِيرًا، فَكَانَتْ سِهَامُهُمُ اثْنَىْ عَشَرَ بَعِيرًا أَوْ أَحَدَ عَشَرَ بَعِيرًا، وَنُفِّلُوا بَعِيرًا بَعِيرًا.
