It is narrated from Hazrat Hudhaifah bin Yaman (may Allah be pleased with him) that, by Allah! I know more than all people about all the tribulations that will occur from now until the Day of Judgment. It was not that the Prophet Muhammad (peace and blessings be upon him) told me something exclusively that he did not tell anyone else, but rather, I was present in the gathering in which the Prophet Muhammad (peace and blessings be upon him) mentioned these matters. Questions were being asked to the Prophet Muhammad (peace and blessings be upon him) regarding tribulations, and the Prophet Muhammad (peace and blessings be upon him) was counting them. Among them, there are three tribulations that will leave nothing untouched; some of them will be like the winds of summer, some will be small, and some will be great. Hudhaifah (may Allah be pleased with him) says that, except for me, all the participants of that gathering have departed from this world.
