17- Food and hygiene:
On the other hand, modern scientific discoveries have confirmed the medical wisdom of prohibiting certain foods and drinks. These include dead animal meats; that were not given enough time to bleed off completely. This can only be guaranteed by the Islamic slaughtering practice of cutting the throat, in such a manner as to allow for the drainage of the blood. Animal blood, also prohibited in Islâm, easily absorbs and promotes bacteria from within and outside sources.
The prohibited pork meat carry a list of dangerous parasites. Tinea, that seriously damage the human organs, including the brain and intestines, is only one type of these parasites. Also pork fat is the most indigestible and highest in cholesterol.
Alcohol, prohibited in Islâm, is considered a great threat to civilization, medically, psychologically and socially, next only to AIDS. Adultery and homosexuality, the main sources of AIDS and other venereal diseases, are also prohibited. Besides, all venues leading to such practices are discouraged through Islamic guidance and legislation.
Much of modern hygienic practices, essential for personal and community health care, have been prescribed by the Prophet (pbuh), who was an illiterate who lived in a primitive community 14 centuries back. These include the periodic washing of the whole body (at least once a week and after every intercourse), and ablution i.e. washing of hands, face, arms and feet; and wiping the hair with water. This is repeated up to five times a day, as a prelude for the five prayers. Tooth brushing with natural (Siwâk), or artificial brush, and gargling the mouth after meals and before prayers are also enacted.
Moderation in food intake, eating slowly in a seated upright position, fetching the proper medication, avoiding infected areas, and even the principle of holding quarantines during epidemics have been ordained by the Prophet of Islâm.
Protection of the environment from the uncontrolled spread of parasites, and the avoidance of rabies infection from dogs are two more examples of practices prescribed in Islâm, centuries earlier than human civilization could know or appreciate the wisdom behind. Citations from the Qur’ân and the Prophet’s “Hadîth” or “Sunnah” (sayings and deeds), relevant to this section, are too numerous to include in this concise work.
