Musannaf Ibn Abi Shayba 3:4675

Yazid ibn Harun narrated to us, he said: Muhammad ibn Ishaq informed us, from Imran ibn Abi Anas, from Hanzala ibn Ali al-Aslami, from Khuffaf ibn Ima ibn Rahda al-Ghifari, who said: The Messenger of Allah (may Allah bless him and grant him peace) led us in the dawn prayer. When he raised his head from the final rak'ah, he said: "May Allah curse Lihyan, Ri'l, Dhakwan, and Usayya, for they disobeyed Allah and His Messenger. As for Aslam, may Allah grant them peace; and as for Ghifar, may Allah forgive them." Then he fell into prostration. When he finished the prayer, he turned his face toward the people and said: "O people, I did not say this myself, but rather Allah said it."
