Huzaifa bin Yaman reported,
People used to ask the Messenger of Allah ﷺ about good, but I would ask him about evil, fearing that it might overtake me.I said, "Messenger of Allah, we were living in ignorance and evil, then Allah brought us this good. Will there be any evil after this good?"He said, "Yes."I asked, "And will there be any good after that evil?"He said, "Yes, but it will be tainted."I asked, "What will taint it?"He said, "A people who guide by other than my guidance. You will recognize some of what they do and reject other parts."I asked, "Will there be any evil after that good?"He said, "Yes, callers at the gates of Hell. Whoever responds to them, they will hurl into it."I said, "Messenger of Allah, describe them to us."He said, "They will be from our own people and speak our language."I asked, "What do you command me to do if that overtakes me?"He said, "Hold fast to the main body of the Muslims and their leader."I asked, "What if they have no main body and no leader?"He said, "Then withdraw from all those factions, even if you must bite onto the root of a tree until death overtakes you in that state."

Sahihعن حذيفة بن اليمان يقول
كان الناس يسألون رسول الله ﷺ عن الخير، وكنت أسأله عن الشر مخافة أن يدركني فقلت: يا رسول الله، إنا كنا في جاهلية وشر، فجاءنا الله بهذا الخير، فهل بعد هذا الخير من شر؟ قال: نعم قلت: وهل بعد ذلك الشر من خير؟ قال: نعم وفيه دخن قلت: وما دخنه؟ قال: قوم يهدون بغير هديي تعرف منهم وتنكر قلت: فهل بعد ذلك الخير من شر؟ قال: نعم دعاة على أبواب جهنم من أجابهم إليها قذفوه فيها قلت: يا رسول الله صفهم لنا قال: هم من جلدتنا ويتكلمون بألسنتنا قلت: فما تأمرني إن أدركني ذلك قال: تلزم جماعة المسلمين وإمامهم قلت: فإن لم يكن لهم جماعة ولا إمام قال: فاعتزل تلك الفرق كلها، ولو أن تعض بأصل شجرة حتى يدركك الموت، وأنت على ذلك.
Bukhari related it in Fitan (7084), and Muslim in Imarah (1847:51), both from Muhammad bin Muthanna, who said, Walid bin Muslim narrated to us, who said, Ibn Jabir narrated to us, who said, Busr bin Ubaydullah Hadrami narrated to me, that he heard Abu Idris Khawlani, that he heard Huzaifa bin Yaman say, and he mentioned it.Muslim also related it right after (52) through the route of Yahya bin Hassan, who said, Muawiya (meaning Ibn Salam) narrated to us, who said, Zayd bin Salam narrated to us, from Abu Salam, who said, Huzaifa bin Yaman said, I said, "Messenger of Allah, we were in a state of evil, and Allah brought good, and now we are in it. Is there any evil beyond this good?" He said, "Yes." I said, "Is there any good beyond that evil?" He said, "Yes." I said, "Is there any evil beyond that good?" He said, "Yes." I said, "How so?" He said, "There will be leaders after me who will not be guided by my guidance and will not follow my sunnah, and men will rise among them whose hearts are the hearts of devils in the bodies of men." He said, I said, "What should I do, Messenger of Allah, if I live to see that?" He said, "You listen and obey the ruler, even if he beats your back and takes your wealth, listen and obey."However, its chain contains a break, because Abu Salam, whose name was Mamtur Habashi, did not hear from Huzaifa bin Yaman 
. Daraqutni said in Tatabbu (p. 226), "This, in my view, is mursal. Abu Salam did not hear from Huzaifa nor from his peers who settled in Iraq, because Huzaifa died some nights after Uthman was killed, and Huzaifa spoke of this matter, which indicates that it is mursal."Hafiz said in the biography of Mamtur Abu Salam in Tahzib (10/296), "He transmitted from Huzaifa and Abu Dharr and others in mursal form."The hadith is sahih, as established through the first chain, and this second chain was mentioned by Muslim as a corroborating narration containing additional material.As for the statement in the hadith, "adhere to the community of the Muslims," Tabari said, "That is, those who are in obedience to the one whom they have agreed to appoint as leader. Whoever breaks his pledge of allegiance has left the community." He said, "And in the hadith is an indication that whenever the people have no leader and the people split into factions, one should not follow anyone into division, but should withdraw from all of them if able, out of fear of falling into evil." See Fath al-Bari (10/37).
