Musannaf Ibn Abi Shayba 3:3282

Waki’ narrated to us, from ‘Abd al-Rahman ibn ‘Abis, from Ibn ‘Abbas, that the Prophet (peace and blessings of Allah be upon him) prayed with them on the day of Eid at the house of Kathir ibn al-Salt. He prayed before the sermon, and he did not mention an adhan nor an iqamah.
