It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) recited Qunoot Nazilah after bowing in the Fajr prayer for a month, and kept invoking curses upon the tribes of Ri'l and Dhakwaan, and said that 'Usayyah has disobeyed Allah and His Messenger.'
