Imam Sadiq (a.s) said: “Do not make fun of people since it will ruin one's honor and dignity. The Prophet's companions used to gather together and tell jokes until the following verse was revealed: “Has not the time arrived for the Believers that their hearts in all humility should engage in the remembrance of God.” [The Holy Quran: Hadid 57:16] Then after the Prophet recited this verse they stopped their joking and vain talk.”
