Huzaifa bin Yaman reported,

People used to ask the Messenger of Allah ﷺ about the good, but I would ask him about the evil, fearing that it might overtake me.I said, "Messenger of Allah, we were in a state of 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 will be cast 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 I live to see that?"He said, "Hold fast to the community of the Muslims and their leader."I asked, "But what if they have no community 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 while you are in that state."

Sahih

عن 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.
