It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that someone asked the Holy Prophet (peace and blessings be upon him): "Which thing will cause people to enter Hell in the greatest numbers?" The Holy Prophet (peace and blessings be upon him) replied: "The two hollow things, that is, the mouth and the private parts." Then it was asked: "Which thing will cause people to enter Paradise in the greatest numbers?" He replied: "Good character."
