Musannaf Ibn Abi Shayba 3:3355

Waki’ narrated to us, from Musa ibn Ubaydah, from Muhammad ibn ‘Amr ibn ‘Ata, from Ibn ‘Abbas, that the Messenger of Allah (may Allah bless him and grant him peace) used to recite in the Eid [prayer]: "Glorify the name of your Lord, the Most High" (Surah Al-A’la). And: "Has there reached you the report of the Overwhelming [event]?" (Surah Al-Ghashiyah).
