Musnad Abu Ya'la al-Mawsili 148:12

Zuhayr ibn Harb narrated to us, Jarir narrated to us, from Sulayman, from Abu Mijlaz, from Anas ibn Malik, who said: The Messenger of Allah (may Allah bless him and grant him peace) performed Qunut for a month after the bowing, supplicating against Ri'l, Dhakwan, and Usayyah, who disobeyed Allah and His Messenger.
