It is transmitted by Rib’i b. Hirash, who narrated it on the authority of Hudhaifa that verily ‘Umar said: Who would narrate to us or who amongst you would narrate to us (and Hudhaifa was one amongst them) what the Messenger of Allah (may peace be upon him) had said about the turmoil? Hudhaifa said: I will, and recited the hadith like that transmitted by Abu Malik on the authority of Rib’i and he observed in connection with this hadith that Hudhaifa remarked: I am narrating to you a hadith and it has no mistake, and said: That it is transmitted from he Messenger of Allah (may peace be upon him).
