Uncertainty In Application Of God's Orders
This question is about the application of a command. A command is based on a reason or cause. If the reason or cause is not there the command doesn’t apply. Prohibition of mocking is based on the reason that it is a bad thing, an unethical ect, it hurts. On the other hand joking and having fun among the friends doesn’t involve any ill intentions, usually. Therefoee it is not forbidden. However if one’s knows that a certain kind of joke may hurt someone, it again incurs prohibition.
