Sahih al-Bukhari 3606
Narrated Hudhaifa bin Al-Yaman:
The people used to ask Allah's Messenger (ﷺ) about good, but I used to ask him about evil for fear that it 
might overtake me. Once I said, "O Allah's Messenger (ﷺ)! We were in ignorance and in evil and Allah has 
bestowed upon us the present good; will there by any evil after this good?" He said, "Yes." I asked, 
"Will there be good after that evil?" He said, "Yes, but it would be tained with Dakhan (i.e. Little 
evil)." I asked, "What will its Dakhan be?" He said, "There will be some people who will lead 
(people) according to principles other than my tradition. You will see their actions and disapprove of 
them." I said, "Will there by any evil after that good?" He said, "Yes, there will be some people who 
will invite others to the doors of Hell, and whoever accepts their invitation to it will be thrown in it 
(by them)." I said, "O Allah's Messenger (ﷺ)! Describe those people to us." He said, "They will belong to us 
and speak our language" I asked, "What do you order me to do if such a thing should take place in my 
life?" He said, "Adhere to the group of Muslims and their Chief." I asked, "If there is neither a group 
(of Muslims) nor a chief (what shall I do)?" He said, "Keep away from all those different sects, even if 
you had to bite (i.e. eat) the root of a tree, till you meet Allah while you are still in that state."
حَدَّثَنَا يَحْيَى بْنُ مُوسَى، حَدَّثَنَا الْوَلِيدُ، قَالَ حَدَّثَنِي ابْنُ جَابِرٍ، قَالَ حَدَّثَنِي بُسْرُ بْنُ عُبَيْدِ اللَّهِ الْحَضْرَمِيُّ، قَالَ حَدَّثَنِي أَبُو إِدْرِيسَ الْخَوْلاَنِيُّ، أَنَّهُ سَمِعَ حُذَيْفَةَ بْنَ الْيَمَانِ، يَقُولُ كَانَ النَّاسُ يَسْأَلُونَ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنِ الْخَيْرِ، وَكُنْتُ أَسْأَلُهُ عَنِ الشَّرِّ مَخَافَةَ أَنْ يُدْرِكَنِي‏.‏ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّا كُنَّا فِي جَاهِلِيَّةٍ وَشَرٍّ، فَجَاءَنَا اللَّهُ بِهَذَا الْخَيْرِ، فَهَلْ بَعْدَ هَذَا الْخَيْرِ مِنْ شَرٍّ قَالَ ‏"‏ نَعَمْ ‏"‏‏.‏ قُلْتُ وَهَلْ بَعْدَ ذَلِكَ الشَّرِّ مِنْ خَيْرٍ قَالَ ‏"‏ نَعَمْ، وَفِيهِ دَخَنٌ ‏"‏‏.‏ قُلْتُ وَمَا دَخَنُهُ قَالَ ‏"‏ قَوْمٌ يَهْدُونَ بِغَيْرِ هَدْيِي تَعْرِفُ مِنْهُمْ وَتُنْكِرُ ‏"‏‏.‏ قُلْتُ فَهَلْ بَعْدَ ذَلِكَ الْخَيْرِ مِنْ شَرٍّ قَالَ ‏"‏ نَعَمْ دُعَاةٌ إِلَى أَبْوَابِ جَهَنَّمَ، مَنْ أَجَابَهُمْ إِلَيْهَا قَذَفُوهُ فِيهَا ‏"‏‏.‏ قُلْتُ يَا رَسُولَ اللَّهِ صِفْهُمْ لَنَا فَقَالَ ‏"‏ هُمْ مِنْ جِلْدَتِنَا، وَيَتَكَلَّمُونَ بِأَلْسِنَتِنَا ‏"‏ قُلْتُ فَمَا تَأْمُرُنِي إِنْ أَدْرَكَنِي ذَلِكَ قَالَ ‏"‏ تَلْزَمُ جَمَاعَةَ الْمُسْلِمِينَ وَإِمَامَهُمْ ‏"‏‏.‏ قُلْتُ فَإِنْ لَمْ يَكُنْ لَهُمْ جَمَاعَةٌ وَلاَ إِمَامٌ قَالَ ‏"‏ فَاعْتَزِلْ تِلْكَ الْفِرَقَ كُلَّهَا، وَلَوْ أَنْ تَعَضَّ بِأَصْلِ شَجَرَةٍ حَتَّى يُدْرِكَكَ الْمَوْتُ وَأَنْتَ عَلَى ذَلِكَ ‏"‏‏.‏
