Hadith 509760
Chapter 21: Jihad - كتاب الجهاد
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم بَعَثَ سَرِيَّةً فِيهَا عَبْدُ اللَّهِ بْنُ عُمَرَ قِبَلَ نَجْدٍ فَغَنِمُوا إِبِلاً كَثِيرَةً فَكَانَ سُهْمَانُهُمُ اثْنَىْ عَشَرَ بَعِيرًا أَوْ أَحَدَ عَشَرَ بَعِيرًا وَنُفِّلُوا بَعِيرًا بَعِيرًا .
Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, sent a raiding party which included Abdullah ibn Umar near Najd. They plundered many camels and their portions were twelve or eleven camels each. They divided it up camel by camel.
