It is narrated from Sayyiduna al-Arqam bin Abi al-Arqam (may Allah be pleased with him) that on the day of Badr the Messenger of Allah (peace and blessings be upon him) said: "Return whatever spoils of war (anfal) you have with you." So Sayyiduna Abu Usayd al-Sa'idi (may Allah be pleased with him) (brought and) put down the sword of Banu al-A'idh bin al-Marzuban. Sayyiduna al-Arqam (may Allah be pleased with him) recognised it and said: "O Messenger of Allah! Grant it to me." So he (peace and blessings be upon him) gave it to him.
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from al-Arqam bin Abi al-Arqam (may Allah be pleased with him) only with this chain; Abu Mus'ab is alone in narrating it."
