We were one day in the company of 'Umar that he said: Who amongst you has preserved in his mind most perfectly the hadith of Messenger of Allah ﷺ in regard to the turmoil as he told about it? I said: It is I. Thereupon he said: You are bold (enough to make this claim). And he further said: How? I said: I heard Messenger of Allah ﷺ as saying: There would (first) be turmoil for a person in regard to his family, his property, his own self, his children, his neighbours (and the sins committed in their connection) would be expiated by fasting, prayer, charity, enjoining good and prohibiting evil. Thereupon 'Umar said: I do not mean (that turmoil on a small scale) but that one which would emerge like the mounting waves of the ocean. I said: Commander of the Faithful, you have nothing to do with it, for the door is closed between you and that. He said: Would that door be broken or opened? I said: No, it would be broken. Thereupon he said: Then it would not be closed despite best efforts. We said to Hudhaifa: Did Umar know the door? Thereupon he said: Yes, he knew it (for certain) just as one knows that night precedes the next day. And I narrated to him something in which there was nothing fabricated. Shaqiq (one of the narrators) said: We dared not ask Hudhaifa about that door. So we requested Masruq to ask him. So he asked him and he said: (By that door, he meant) 'Umar.  

أَيُّكُمْ يَحْفَظُ حَدِيثَ رَسُولِ اللَّهِ ﷺ فِي الْفِتْنَةِ كَمَا قَالَ قَالَ فَقُلْتُ أَنَا قَالَ إِنَّكَ لَجَرِيءٌ وَكَيْفَ قَالَ قَالَ قُلْتُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ فِتْنَةُ الرَّجُلِ فِي أَهْلِهِ وَمَالِهِ وَنَفْسِهِ وَوَلَدِهِ وَجَارِهِ يُكَفِّرُهَا الصِّيَامُ وَالصَّلاَةُ وَالصَّدَقَةُ وَالأَمْرُ بِالْمَعْرُوفِ وَالنَّهْىُ عَنِ الْمُنْكَرِ فَقَالَ عُمَرُ لَيْسَ هَذَا أُرِيدُ إِنَّمَا أُرِيدُ الَّتِي تَمُوجُ كَمَوْجِ الْبَحْرِ قَالَ فَقُلْتُ مَا لَكَ وَلَهَا يَا أَمِيرَ الْمُؤْمِنِينَ إِنَّ بَيْنَكَ وَبَيْنَهَا بَابًا مُغْلَقًا قَالَ أَفَيُكْسَرُ الْبَابُ أَمْ يُفْتَحُ قَالَ قُلْتُ لاَ بَلْ يُكْسَرُ قَالَ ذَلِكَ أَحْرَى أَنْ لاَ يُغْلَقَ أَبَدًا قَالَ فَقُلْنَا لِحُذَيْفَةَ هَلْ كَانَ عُمَرُ يَعْلَمُ مَنِ الْبَابُ قَالَ نَعَمْ كَمَا يَعْلَمُ أَنَّ دُونَ غَدٍ اللَّيْلَةَ إِنِّي حَدَّثْتُهُ حَدِيثًا لَيْسَ بِالأَغَالِيطِ قَالَ فَهِبْنَا أَنْ نَسْأَلَ حُذَيْفَةَ مَنِ الْبَابُ فَقُلْنَا لِمَسْرُوقٍ سَلْهُ فَسَأَلَهُ فَقَالَ عُمَرُ  

This hadith has been narrated on the authority of Hudhaifa through other chains of transmitters also.  

عَنِ الأَعْمَشِ بِهَذَا الإِسْنَادِ نَحْوَ حَدِيثِ أَبِي مُعَاوِيَةَ وَفِي حَدِيثِ عِيسَى عَنِ الأَعْمَشِ عَنْ شَقِيقٍ قَالَ سَمِعْتُ حُذَيْفَةَ يَقُولُ  

Who would narrate to us (the ahadith pertaining to turmoil) and he reported a hadith similar to these ahadith.  

يُحَدِّثُنَا عَنِ الْفِتْنَةِ وَاقْتَصَّ الْحَدِيثَ بِنَحْوِ حَدِيثِهِمْ  

I came on the day of Jaraʿa that a person was (found) sitting. I said: They would shed their blood today. That person said: By Allah. not at all. I said: By Allah, of course, they would do it. He said: By Allah, they would not do it. I said: By Allah, of course, they would do it. He said: By Allah, they would not do it, and I have heard a hadith of Messenger of Allah ﷺ which I am narrating to you in this connection. I said: You are a bad seat fellow. I have been opposing you since morning and you are listening to me in spite of the fact that you have heard a hadith from Allah's Apostle ﷺ (contrary to my statement). I myself felt that there was no use of this annoyance. (He could tell me earlier that it was a hadith of the Prophet (may peace be upon him], and I would not have opposed him at all.) I turned my face toward him and asked him and he was Hadrat Hudhaifa.  

جُنْدُبٌ جِئْتُ يَوْمَ الْجَرَعَةِ فَإِذَا رَجُلٌ جَالِسٌ فَقُلْتُ لَيُهَرَاقَنَّ الْيَوْمَ هَا هُنَا دِمَاءٌ فَقَالَ ذَاكَ الرَّجُلُ كَلاَّ وَاللَّهِ قُلْتُ بَلَى وَاللَّهِ قَالَ كَلاَّ وَاللَّهِ قُلْتُ بَلَى وَاللَّهِ قَالَ كَلاَّ وَاللَّهِ إِنَّهُ لَحَدِيثُ رَسُولِ اللَّهِ ﷺ حَدَّثَنِيهِ قُلْتُ بِئْسَ الْجَلِيسُ لِي أَنْتَ مُنْذُ الْيَوْمِ تَسْمَعُنِي أُخَالِفُكَ وَقَدْ سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ ﷺ فَلاَ تَنْهَانِي ثُمَّ قُلْتُ مَا هَذَا الْغَضَبُ فَأَقْبَلْتُ عَلَيْهِ وَأَسْأَلُهُ فَإِذَا الرَّجُلُ حُذَيْفَةُ
