By Allah, I have the best knowledge amongst people about every turmoil which is going to appear in the period intervening me and the Last Hour; and it is not for the fact that Messenger of Allah ﷺ told me something confidentially pertaining to it and he did not tell anybody else about it, but it is because of the fact that I was present in the assembly in which he had been describing the turmoil. and he especially made a mention of three turmoils which would not spare anything and amongst these there would be turmoils like storms in the hot season. Some of them would be violent and some of them would be comparatively mild. Hudhaifa said: All (who were present) except I have gone (to the next world). (Using translation from Muslim 2891a)
أَنْ يَكُونَ رَسُولُ اللهِ ﷺ حَدَّثَنِي مِنْ ذَلِكَ شَيْئًا أَسَرَّهُ إِلَيَّ لَمْ يَكُنْ حَدَّثَ بِهِ غَيْرِي وَلَكِنَّ رَسُولَ اللهِ ﷺ قَالَ وَهُوَ يُحَدِّثُ مَجْلِسًا أَنَا فِيهِ سُئِلَ عَنِ الْفِتَنِ وَهُوَ يَعُدُّ الْفِتَنَ فِيهِنَّ ثَلَاثٌ لَا يَذَرْنَ شَيْئًا مِنْهُنَّ كَرِيَاحِ الصَّيْفِ مِنْهَا صِغَارٌ وَمِنْهَا كِبَارٌ قَالَ حُذَيْفَةُ فَذَهَبَ أُولَئِكَ الرَّهْطُ كُلُّهُمْ غَيْرِي
