It is narrated from Sayyiduna Khafaf bin Ima’ (may Allah be pleased with him) that once the Prophet (peace and blessings of Allah be upon him) led us in the Fajr prayer. When he raised his head from the bowing (ruku’) of the second rak’ah, he recited the Qunoot Nazilah and made this supplication:“May Allah’s curse be upon the tribe of Lihyan, Ra’l, and Dhakwaan, and the tribe of ‘Usayyah has disobeyed Allah and His Messenger. May Allah grant safety to the tribe of Aslam, and may Allah forgive the tribe of Ghifar.”Then he went into prostration, and after completing the prayer, he said to the people:“O people! By Allah! These words were not said by me, but Allah Himself has said them.”
