Hazrat Hasan (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Because of the intercession of one man from my Ummah, as many people from the tribe of Rabi’ah and the tribe of Mudar will enter Paradise. Hazrat Huwaisib (may Allah have mercy on him) says that we asked Hazrat Hasan (may Allah be pleased with him): Were you told the name of this person? He (may Allah be pleased with him) replied: Yes! Hazrat Uwais Qarni (may Allah be pleased with him).
