Mukhtasar Bukhari

`Sayyiduna Hudhayfah bin Yaman (may Allah be pleased with him) says:` People used to ask the Messenger of Allah (peace and blessings of Allah be upon him) about good things, and I used to ask him about evils (which would occur after him) out of fear that I might fall into them. I said, "O Messenger of Allah! We were in ignorance and evil, then Allah brought us this goodness through you. Will there be evil after this goodness?" He (peace and blessings of Allah be upon him) said, "Yes." I said, "Will there be goodness after that evil?" He (peace and blessings of Allah be upon him) said, "Yes, but there will be smoke in it." I asked, "What is smoke?" He said, "There will be people who will not follow my way; some of their deeds will be good and some bad." I said, "Will there be evil after that goodness?" He said, "Yes! There will be people who will stand at the gates of Hell, calling towards it; whoever responds to their call, they will throw him into Hell." I said, "O Messenger of Allah! Describe them to us." He said, "They will be from our people (Muslims) outwardly, and will speak our language." I said, "If I live to see that time, what do you command me to do?" He said, "Stay with the group of Muslims and their rightful leader." I said, "What if there is no group or leader at that time?" He (peace and blessings of Allah be upon him) said, "Then keep away from all those sects, even if you have to chew the root of a tree (due to hunger) until death overtakes you; this will be better for you than joining them."
