What did the Prophet Muhammad (peace be upon him) pray when he cursed the tribes of Lihyan, Ri'l, Dhakwan, and 'Usayya?
 Khufaf b. Ima' al-Ghifari reported that the Messenger of Allah (may peace be upon him) aid in prayer:                      0 Allah I curse the tribes of Lihyan, Ri'l, Dhakwan, and 'Usayya for they disobeyed Allah and His Messenger (may peace be upon him). Allah pardoned (the tribe of) Ghifar and Allah granted protection to (the tribe of) Aslam
