The people used to ask Messenger of Allah ﷺ about good, but I used to ask him about evil for fear that it might overtake me. Once I said, "O Messenger of Allah 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 Messenger of Allah 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."  

أَنَّهُ سَمِعَ حُذَيْفَةَ بْنَ الْيَمَانِ يَقُولُ كَانَ النَّاسُ يَسْأَلُونَ رَسُولَ اللَّهِ ﷺ 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  

The Prophet ﷺ said, "Whoever disapproves of something done by his ruler then he should be patient, for whoever disobeys the ruler even a little (little = a span) will die as those who died in the Pre-lslamic Period of Ignorance. (i.e. as rebellious Sinners).  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ كَرِهَ مِنْ أَمِيرِهِ شَيْئًا فَلْيَصْبِرْ فَإِنَّهُ مَنْ خَرَجَ مِنَ السُّلْطَانِ شِبْرًا مَاتَ مِيتَةً جَاهِلِيَّةً
