Hazrat Ka'b bin Ujrah (may Allah be pleased with him) narrates that indeed the Messenger of Allah (peace and blessings be upon him) mentioned the coming of a tribulation, and he described it as being very near. Then a man passed by whose head was covered with a cloth. The Prophet (peace and blessings be upon him) said: On that day, this man and his group will be upon guidance. So a person went after him, caught him by the shoulder, turned his face towards the Messenger of Allah (peace and blessings be upon him), and asked: This man? The Prophet (peace and blessings be upon him) replied: Yes! And that was Hazrat Uthman (may Allah be pleased with him).
