Humor is a manifestation of moral sophistication, and evidence of a pure mind and extraordinary genius. The Arabs loved to laugh, welcomed those who laughed, made them close, and gave them generous gifts. They used to choose beautiful names for their children, such as: Al-Dahhak, Wadah, Bishr, Farhat, etc. The truth is that when we laugh, we move only four muscles in our body, while crying moves twenty-three muscles. This is why medicine prefers laughter, not crying. Laughter also affects the body and mind because it stimulates blood circulation, which increases vitality and activity, and the person feels high and happy.
