Musannaf Ibn Abi Shayba 28:897

Waki' narrated to us, he said: Isma'il bin Abi Khalid narrated to us, I heard Ibn Abi Awfa saying: The Messenger of Allah (may Allah bless him and grant him peace) supplicated against the Confederates (al-Ahzab) and said: "O Allah, Revealer of the Book, Swift in reckoning, Defeater of the Confederates, defeat them and shake them."
