Sahih Muslim 144 b
It is narrated on the authority of Rib'i (b. Hirash). When Hudhaifa came from 'Umar he sat down to narrate to us and said:
Verily yesterday when I was sitting with the Commander of the believers he asked his companions: When amongst you retains in his memory the utterance of the Messenger of Allah (ﷺ) with regard to the turmoil? -and he cited the hadith like the hadith narrated on the authority of Abu Khalid, but he did not mention the exposition of his words (Murbaddan) and (Mujakhiyyan).
وَحَدَّثَنِي ابْنُ أَبِي عُمَرَ، حَدَّثَنَا مَرْوَانُ الْفَزَارِيُّ، حَدَّثَنَا أَبُو مَالِكٍ الأَشْجَعِيُّ، عَنْ رِبْعِيٍّ، قَالَ لَمَّا قَدِمَ حُذَيْفَةُ مِنْ عِنْدِ عُمَرَ جَلَسَ فَحَدَّثَنَا فَقَالَ إِنَّ أَمِيرَ الْمُؤْمِنِينَ أَمْسِ لَمَّا جَلَسْتُ إِلَيْهِ سَأَلَ أَصْحَابَهُ أَيُّكُمْ يَحْفَظُ قَوْلَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي الْفِتَنِ وَسَاقَ الْحَدِيثَ بِمِثْلِ حَدِيثِ أَبِي خَالِدٍ وَلَمْ يَذْكُرْ تَفْسِيرَ أَبِي مَالِكٍ لِقَوْلِهِ ‏
"‏ مُرْبَادًّا مُجَخِّيًا ‏"‏ ‏.‏
