Narrated Abu Huraira:
Tufail bin `Amr Ad-Dausi and his companions came to the Prophet (ﷺ) and said, "O Allah's Messenger (ﷺ)! The people of the tribe of Daus disobeyed and refused to follow you; so invoke Allah against them." The people said, "The tribe of Daus is ruined." The Prophet (ﷺ) said, "O Allah! Give guidance to the people of Daus, and let them embrace Islam."
