Warning against the leprosy disease, the prophet Mohammed (PBUH) said “Escape away from the Leprous the way you escape away from the Lion” [Refer to Bukhari] The modern Medical science discovered that leprosy disease is one of the most dangerous skin diseases which gets transferred by the Leprosy microbe which has been seen and recognized before one hundred years, however, still (modern medical circles could not find an effective cure to this disease or control it. Leprosy affects the terminals of the nerves such as the limbs. It makes the leprous lose the sense of feeling. Therefore, he does not feel heat or cold. He may not even the piercing of at horn to his skin. The leprous faces atrophy of the muscles of arms and legs. Ulcers spread on his body particularly on hand and legs. Bones erode and the leprous loses his fingers. It may affected the cornea of the eyes & makes him blind, it may also affect his testis & this means that the leprous may loose fertility & becomes sterile. Leprosy is of two kinds, the knot leprosy. It affects the people with weak immunization system. It appears in the form of different size knots. It spreads all over the body, particularly, the face and gives it a special shape which makes it resemble the face of a lion. It also causes hair drop. It may also affect the mucous membrane & creates bleeding. The numbed knots Leprosy is the second type of leprosy which appears on the skin in the form of pale knots which have different shapes and sizes. They are characterized by loss of sense, sweating and loss of the skin pigment. This type of leprosy affects people who have good immunization system. The greatness of the directive of the prophet (PBUH) appears in the fact that he advised people into to gaze at leprous. He said “Don’t gaze at Leprous” [Refer to Irshad Elsari to Sharh of Bukhari]. The modern science proved that when the leprous sees a healthy or normal person, he gazes at him and then suffers from psychological pain. Therefore, the advice of the prophet wanted to respect the feelings of the leprous. The saying of the prophet (PBUH) which asked people to run away from the leprous as they run away from the lion shows the dangerous nature of this disease which can be transferred easily and its overwhelming nature. Modern science also advised people to avoid leprosy people so long as the disease they nurse is active and not neutralized and its activity is not suspended by the use of the available resistant.
