Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: Ghazwa of Khaibar
Narrated 'Anbasa bin Sa`id:
Abu Huraira came to the Prophet (ﷺ) and asked him (for a share from the Khaibar booty). On that, one of the sons of Sa`id bin Al-`As said to him, "O Allah's Messenger (ﷺ)! Do not give him." Abu Huraira then said (to the Prophet (ﷺ) ) "This is the murderer of Ibn Qauqal." Sa`id's son said, "How strange! A guinea pig coming from Qadum Ad-Dan!"
