Question

I live in Russia where I am studying. Most of our professors are communists who do not believe in the existence of the Creator. One of them said to us: “How can this God of yours command you not to eat and drink during the day when this is damaging to the health?” How do you advise us to respond to this communist, may Allaah humiliate him?.

Praise be to Allah.
    Fasting – as well as being basically an act of worship that 
    is prescribed in Islam and an obligation enjoined by Allaah, is also one of 
    the most beneficial of remedies and most effective means of strengthening 
    one’s body. This is according to the testimony of non-Muslim doctors, let 
    alone Muslim ones. 

    Fasting plays an effective role in treating psychological 
    problems and strengthening the will-power of the fasting person, softening 
    his feelings, and making him love to do good and keep away from 
    argumentative and hostile tendencies; it also increases his spiritual 
    feelings. So it strengthens his personality and makes him more able to bear 
    problems and burdens. Undoubtedly this is reflected positively in a person’s 
    health. 

    This is one aspect. From another angle, fasting also plays a 
    role in treating many physical disorders, such as diseases of the digestive 
    system like gastritis, irritable bowel syndrome, liver diseases and 
    indigestion, as well as treating obesity, hardening of the arteries, high 
    blood pressure, angina, asthma, etc. 

    The Swiss doctor Barcellus wrote: 

    The benefit of hunger as a remedy is many times better than 
    using medicines. Doctor Helb used to forbid his patients to eat for several 
    days, then he would offer them light meals. In general, fasting plays a role 
    in destroying the worn-out tissues at the time of hunger, then rebuilds them 
    when food is ingested. This is the reason why some scientists, including 
    Pashutin, regard fasting as a means of restoring youth. 

    Tom Burns of the Columbia School of Journalism says: I regard 
    fasting as an experience which is deeply spiritual more than physical. 
    Despite the fact that I started to fast with the aim of losing excess 
    weight, I realized that fasting is very beneficial for the mind. It helps me 
    to see with greater clarity and to develop new thoughts and to focus my 
    feelings. Within only a few days of starting my fast in the spa I began to 
    feel that I was passing through a very spiritual experience. 

    Of course fasting may be harmful and extremely difficult for 
    some people in certain situations; Allaah has exempted them from fasting – 
    such as those who are sick and those who are traveling. 

    Moreover the benefits of fasting come when one adheres to the 
    etiquette of fasting, such as delaying suhoor, hastening to break the fast, 
    not being extravagant in the manner or amount of food eaten, and avoiding 
    being extravagant in serving a large variety of foods. 

    The Encyclopaedia Britannica says: Most religions enjoin 
    fasting and it it is something that people used to do even at times other 
    than religious occasions; some individuals fast in response to human nature. 
     

    In the twentieth century a number of books appeared in 
    America and Europe which spoke of the medical benefits of fasting. There was
    Treating sickness by fasting by Shelton; Medical Fasting: The 
    Ideal Nutritional System by Alan Coutt; Fasting, the Elixir of Life 
    by Enrique Tanner; Return to a Healthy Life through Medical Fasting 
    by Watzener. 

    Fasting is of great benefit in treating some diseases of the 
    heart, because 10% of the blood that the heart pumps to the body goes to the 
    digestive system during the digestive process; this amount is reduced during 
    fasting, when the digestive process does not occur during the day. This 
    means that the heart works less and can rest more. 

    Fasting is also used to treat skin diseases, because if the 
    amount of water in the blood is reduced, the amount of water in the skin is 
    also reduced. 

    It increases the skin’s impermeability and resistance to 
    bacterial disease. 

    It reduces the extent of skin diseases that can spread over a 
    large area of the body such as psoriasis. 

    It reduces allergies and other skin problems.  

    Fasting reduces toxic secretions in the intestines and 
    reduces the fermentation that can lead to ulcers. 

    These are some of the health benefits of fasting, from which 
    you may understand that what that communist atheist says has no sound 
    basis. 

    Moreover we fast in obedience to the command of Allaah Who 
    has enjoined us to fast, as He says (interpretation of the meaning): 

    “O you who believe! Observing As-Sawm (the fasting) is 
    prescribed for you as it was prescribed for those before you, that you may 
    become Al-Muttaqoon (the pious”

    [al-Baqarah 2:183]

    If Allaah commanded us to kill ourselves we would do it in 
    order to please our Lord, but we believe with certainty of faith that He 
    would never command us to do anything but that which is in our best 
    interests in this world and in the Hereafter. 

    And Allaah knows best.
