It is narrated from Sayyiduna Urwah bin al-Zubayr (may Allah be pleased with him) that among the allies of Banu Zuhrah bin Kilab who took part in the Battle of Badr was Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him). Urwah further narrates that among those who made the first emigration to Abyssinia, before the departure of Sayyiduna Ja'far bin Abi Talib (may Allah be pleased with him), was Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him).
