Musnad Ahmad 303:24

Bahz narrated to us, he said: Hammam narrated to us, Qatadah narrated to us, from Mutarrif, from his father, that he entered upon the Prophet, may Allah bless him and grant him peace, and heard him saying: He mentioned the like of the hadith of ‘Affan, and he did not mention the statement of Qatadah.
