Qatadah narrates: Sayyiduna Zubayr (may Allah be pleased with him) led the funeral prayer of Sayyiduna Uthman al-Ghani (may Allah be pleased with him), and it was he who buried him, because Sayyiduna Uthman (may Allah be pleased with him) had made a bequest concerning him.
Ahmad recorded it, and its narrators are the narrators of the Sahih, but the narrator Qatadah did not live in the time of this incident.
