 laughter has a place and a measure and joking has a place and a measure. when someone exceeds them and someone falls short of them the excess becomes a mistake and the deficiency becomes a deficiency.
وللضحك موضع وله مقدار، وللمزح موضع وله مقدار، متى جازهما أحد، وقصر عنهما أحد، صار الفاضل خطلا ٤ ، والتقصير نقصا.
