It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) assigned the belongings (of the slain enemy) to the one who killed him.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Masad bin Uqbah except Umar bin Ayyub; Abu Hashim is alone in narrating it."
