Hadeeth of Hudhafyah "Indeed we used to be in Ignorance and Evil"

Hudhayfah ibn Al-Yamaan, may Allaah be pleased with him, said: “The people used to ask Allaah’s Messenger ﷺ about the good; I used to ask him about the evil for fear that it would catch hold of me. I said: ‘O Allaah’s Messenger, indeed we used to be in ignorance and evil, then Allaah brought to us this good. So will there be any evil after this good?’ He said: ‘Yes.’ I said: ‘And after that evil will there be any good?’ He said: ‘Yes, but it will be tainted.’ I said: ‘What will be its taint?’ He said: ‘A people who will guide by other than my guidance; you will recognize them and disapprove of them.’ I said: ‘Will there be any evil after that good?’ He said: ‘Yes; callers to the gates of the Hellfire. Whoever responds to their call, then they will toss him into it.’ I said: ‘O Allaah’s Messenger, describe them for us.’ He said: ‘They are from our people and speak with our tongue.’ I said: ‘What do you command me to do if I should encounter them?’ He said: ‘Cling to the Jamaa’ah of the Muslims and their Imaam.’ I said: ‘What if they have no Jamaa’ah and no Imaam?’ He said: ‘Then stay away from all of those groups even if you must bite on to the trunk of a tree until death overtakes you while you are in that state.’” Saheeh Al-Bukhari: Book of Virtues, Chapter: The Signs of Prophethood in Al-Islaam. Hadeeth number: 3606 ‘Cling to the Jamaa’ah of the Muslims and their Imaam.’ I said: ‘What if they have no Jamaa’ah and no Imaam?’ He said: ‘Then stay away from all of those groups even if you must bite on to the trunk of a tree until death overtakes you while you are in that state.’
