Hudhaifa reported that Umar said:

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

وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ جَامِعِ بْنِ أَبِي رَاشِدٍ، وَالأَعْمَشُ، عَنْ أَبِي وَائِلٍ، عَنْ حُذَيْفَةَ، قَالَ قَالَ عُمَرُ مَنْ يُحَدِّثُنَا عَنِ الْفِتْنَةِ، وَاقْتَصَّ الْحَدِيثَ، بِنَحْوِ حَدِيثِهِمْ ‏.‏
