Musnad Ahmad 25:1370

Yahya narrated to us, from Ibn Jurayj, Ata’ narrated to me, from Ibn Abbas—he said: And he did not hear it [directly]—he said: "The Prophet of Allah, may Allah bless him and grant him peace, sent me at the time of dawn from Jam' [Muzdalifah] with the baggage of the Prophet of Allah, may Allah bless him and grant him peace."
