It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) gave Sayyiduna Uthman (may Allah be pleased with him) a share of the spoils of the Battle of Badr, although he had not taken part in Badr.
Imam al-Tabarani (may Allah have mercy on him) said: "Only Abu Awanah narrated this hadith from Uthman bin Abdullah bin Mawhab, and Abu Qutaybah is alone in narrating it."
