Sahih Muslim, 370

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)

Rapporté par Rib’i ibn Hirash رضي الله عنه : Quand Hudhayfa est revenu de chez Omar رضي الله عنه, il s’est assis pour nous raconter : « Hier, alors que j’étais avec le Commandeur des croyants, il a demandé à ses compagnons : “Qui parmi vous se souvient des paroles du Messager d’Allah ﷺ à propos des troubles ?” » Puis il a rapporté le hadith comme celui transmis par Abu Khalid, mais sans expliquer les mots “Murbaddan” et “Mujakhiyyan”
