Narrated Abu Wail

Someone said to Usama, "Will you not talk to this (Uthman)?" Usama said, "I talked to him (secretly) without being the first man to open an evil door. I will never tell a ruler who rules over two men or more that he is good after I heard Allah's Messenger (ﷺ) saying, 'A man will be brought and put in Hell (Fire) and he will circumambulate (go around and round) in Hell (Fire) like a donkey of a (flour) grinding mill, and all the people of Hell (Fire) will gather around him and will say to him, O so-and-so! Didn't you use to order others for good and forbid them from evil?' That man will say, 'I used to order others to do good but I myself never used to do it, and I used to forbid others from evil while I myself used to do evil.' "
