It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "Do not laugh excessively, for excessive laughter deadens the heart."

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) came to a group of his companions who were laughing and talking. He (peace and blessings be upon him) said: "By Him in Whose hand is my soul, if you knew what I know, you would laugh little and weep much." Then the Prophet (peace and blessings be upon him) went back and made the people weep, and Allah the Exalted revealed to him: "O Muhammad! Why do you make My servants despair?" So the Prophet (peace and blessings be upon him) returned and said: "Rejoice, remain steadfast, and strive to do your deeds correctly."
