It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that once I was walking with the Noble Prophet (peace and blessings be upon him) when the Noble Prophet (peace and blessings be upon him) said: "There is something other than the Dajjal from which I fear for my Ummah the most." He repeated this sentence three times. I asked, "O Messenger of Allah! What is that thing from which you fear for your Ummah the most, and it is other than the Dajjal?" The Noble Prophet (peace and blessings be upon him) said: "Misguiding leaders."
