Thawban narrated that the Messenger of Allah(s.a.w) said:
“I only fear for my Ummah from the misguiding A’immah.” He said that the Messenger of Allah(s.a.w) said: “There will never cease to be a group from my Ummah manifest upon the truth, they will not be harmed by those who forsake them until Allah’s Decree comes.”
