Sahih al-Bukhari, Volume 5, Book 59, Hadith 627 (USC-MSA) ⓘ
Narrated Ibn `Umar: The Prophet sent a Sariya towards Najd and I was in it, and our share from the booty amounted to twelve camels each, and we were given an additional camel each. So we returned with thirteen camels each.
حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا أَيُّوبُ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ بَعَثَ النَّبِيُّ صلى الله عليه وسلم سَرِيَّةً قِبَلَ نَجْدٍ، فَكُنْتُ فِيهَا، فَبَلَغَتْ سِهَامُنَا اثْنَىْ عَشَرَ بَعِيرًا، وَنُفِّلْنَا بَعِيرًا بَعِيرًا، فَرَجَعْنَا بِثَلاَثَةَ عَشَرَ بَعِيرًا.
