It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that he said: "Which of you will narrate to us a hadith he heard from the Messenger of Allah (peace and blessings be upon him) about the fitnah (trial)?" At this Sayyiduna Hudhayfah (may Allah be pleased with him) said: "I will narrate it to you just as he (peace and blessings be upon him) said it." Sayyiduna Umar (may Allah be pleased with him) said: "Indeed, you are bold in (narrating) it; so narrate." He said: "A man's trial concerning his family, his wealth, his children and his neighbour is expiated by prayer, fasting, enjoining good and forbidding evil." Sayyiduna Umar (may Allah be pleased with him) said: "I am not asking you about this; rather, I am asking about the fitnah that will surge like the waves of the sea." Sayyiduna Hudhayfah (may Allah be pleased with him) said: "O Commander of the Believers, you have nothing to fear from it, for between you and it there is a closed door." Sayyiduna Umar (may Allah be pleased with him) asked: "Will that door be opened or will it be broken?" He replied: "Rather, it will be broken." Sayyiduna Umar (may Allah be pleased with him) said: "Then it will never be closed until the Day of Resurrection."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Isa (may Allah have mercy on him) except Ali bin Abi Bakr (may Allah have mercy on him)."
