Al-Mughirah bin Hakim narrates: I asked Sayyiduna Abdullah bin Sahl (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)."
Al-Tabarani recorded it, and its narrators are the narrators of the Sahih, except Abdullah bin Ahmad, and he is thabt (firmly reliable).
