It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) once went to visit a sick person "who had a fever." Hazrat Abu Huraira (may Allah be pleased with him) was also with him. The Noble Prophet (peace and blessings be upon him) said to him: Rejoice, for Allah Almighty says: I impose My fire upon My believing servant in this world so that the portion of the Fire he has in the Hereafter is fulfilled in this world itself.
