Sahih Muslim, Chapter: Faith (Kitab Al Iman)

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).
