Sayyiduna Hudhayfah bin Yaman (may Allah be pleased with him) said: By Allah! Among all people, I have the most knowledge about the tribulations that will occur from today until the Day of Resurrection. The reason for this is not that the Prophet (peace and blessings be upon him) told me secret things that he did not tell others. The matter is that in one gathering, the Messenger of Allah (peace and blessings be upon him) was asked about tribulations, and I was also present in that assembly. The Prophet (peace and blessings be upon him) began to enumerate and explain the tribulations. He (peace and blessings be upon him) said: Among them, there will be three tribulations that, due to their severity, will leave nothing untouched. Some tribulations will be like the summer winds, and some will be small, and some will be large. Sayyiduna Hudhayfah (may Allah be pleased with him) said: All the people who were present in that gathering have passed away; only I am alive.
