Sahih al-Bukhari 3134
Narrated Nafi` from Ibn `Umar:
Allah's Messenger (ﷺ) 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 صلى الله عليه وسلم بَعَثَ سَرِيَّةً فِيهَا عَبْدُ اللَّهِ قِبَلَ نَجْدٍ، فَغَنِمُوا إِبِلاً كَثِيرًا، فَكَانَتْ سِهَامُهُمُ اثْنَىْ عَشَرَ بَعِيرًا أَوْ أَحَدَ عَشَرَ بَعِيرًا، وَنُفِّلُوا بَعِيرًا بَعِيرًا‏.‏
