Majma al-Zawaid — Hadith 10043

Al-Mughirah bin Hakim narrates: I asked Sayyiduna Abdullah bin Sa'd bin Khaythamah al-Ansari (may Allah be pleased with him): "Did you take part in the battle of Badr?" He replied: "Yes, and (I took part) in the pledge of al-Aqabah too, along with my father."
Al-Tabarani recorded it, and its narrators are the narrators of the Sahih.
