Sahih Muslim Book 1, Hadith Number 268.

Chapter : Removal of Trustworthiness and Faith from some hearts and appearance of discord therein.

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 (may peace be upon him) 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).
