Aishah (May Allah be pleased with her) reported: I have never seen Messenger of Allah (PBUH) Laughing so heartily that his uvula could be seen. He used to smile only.
[Al-Bukhari and Muslim]

Commentary: To laugh much is one of the sign of indifference to the remembrance of Allah. Besides, the habit of laughing aloud robs away the dignity and impressiveness of a man.
