Undoubtedly...
Undoubtedly, this similarity establishes the need for cooperation among members of society and awakens man’s emotions to strengthen his relationship with other individuals, sympathize and cooperate with them, and not deprive them of the resources he may acquire. This reasonable similarity that can prove very useful and is rooted in traditions reported from the Noble Messenger ( s ) and Imam as-Sadiq ( ‘a ).
When one part feels pain, the other parts remain restless without sleep day and night.” [^1] As you see, His Holiness compares the Islamic society and the faithful to a body and Sa’di has generalized it and likened the human to a body. An analogy is meant to highlight that aspect in one being whose existence in the other is not well known. Therefore, not all attributes and qualities of one thing [ mushabbahun bih ] should be passed to the thing likened [ mushabbah ].
For example, if we describe a brave man as a lion, it means that we want to highlight his quality of bravery. It does not imply that he also has a mane, or walks on all fours! Ways of comparing society to the human body Society and an individual can be compared to the human body as possessing diverse yet well-coordinated systems and organs that are contributory in the subsistence and growth of man. Society also has various institutions that generally facilitate its movement.
For example, there is a system in the body called circulatory system which facilitates the circulation of blood in the body and whose center is the heart. The heart pumps the blood which is produced through the activity and coordination of the spleen, stomach and liver. In the end, through the veins, arteries and finally aorta, the blood reaches the cells and makes their subsistence possible.
The circulatory system has organs such as the heart, veins and arteries, which transmit the blood throughout the body. The blood that flows in the veins must have oxygen so as to ensure the subsistence of cells. As such, the lungs and other organs of the respiratory system provide oxygen to the body which, together with the blood, is distributed throughout the body.
