The Qur'an is not a book of medicine or of health sciences, but in it there are hints which lead to guidelines in health and diseases. Prophet Mohammed (peace and blessings be upon him) has been sent as an example to mankind so his traditions in matters of health and personal hygiene are also a guide for his followers.
We start our discussion with the following verse: "Everything good that happens to you (O Man) is from God, everything bad that happens to you is from your own actions". (Qur'an 4:79).
The human body can be compared to some degree with a machine created by man. The fascinating tape recorder has many mechanical and electronic parts but life does not come to it till an electrical current is passed through.
Similarly, in the components of the human body there are the anatomic parts and fluids but also the spirit (the soul). As the care of a machine requires keeping it clean, giving it some rest, and passing electricity of proper voltage, and using it carefully and wisely, so are there requirements for the body and of the body as a whole.
Before we come to the physical care of human body, let us talk about the spiritual care. The spiritual care involves the acts of worship. The problem is that Iman (faith) cannot be translated into belief, nor Salaat into prayer, Nor Wudu into washing hands, face and feet nor; Sawm into fasting nor Zakat into charity nor Hajj into pilgrimage to Mecca.
Belief in God is the first and foremost important need for spiritual stability. Belief in God includes belief in His attributes, His angels, His books, the Day of Judgment, the Heaven and Hell and belief that - all good and bad is within His reach.
Imam Rumi has called faith being superior to prayers. In illness, according to Imam Ghazali, the awareness of God increases and man becomes closer to God by realizing his own weakness.
Without true belief, neither our prayer, nor charity, nor fasting nor pilgrimage will be accepted. The essence of belief is to rid ourselves of all false gods around us, or within us, and to worship no one except God alone.
B. Salat: There are three health aspects of Salat:
I. Wudu: Washing all the exposed areas of the body, hand, feet, face, mouth, nostrils etc. 5 times a day is a healthy preventive procedure. Hand washing is being emphasized more and more in hospitals now in order to prevent the spread of germs. However, non-Muslims did not know that handwashing is so important - it has been ordered in Qur'an (5:7) 1400 years ago. And for complete cleanliness bathing is advised (4:43).
2. Recitation of Qur'an:
This has a healing effect on the body, mind and heart. These healing effects are due to the effect of sound (echo) and the meaning. The letter Alif resounds unto the echoes to heart and the letter YA resounds unto echoes to the pineal gland in the brain.
The movements in Salat are mild, uniform, and involve all muscles and joints. The caloric output is desired to keep the energy balance.
C. Zakat (Charity):
The word itself means purification and growth. Here it is meant to imply the purification of legitimately earned wealth. Many of our crimes are committed with money or for the love of money, and in the love of money one becomes violent in behavior. "And he is violent in his love of wealth" (Qur'an 100:8).
In Islam the ownership of wealth belongs to God. We are the disposers of that trust. Therefore, this concept establishes peace at heart and our behavior in the loss of money or unusual gain. In either way, we thank God.
The Islamic fasting: Islamic fasting is prescribed as way training of our mind and body in self-restraints. "O you who believe fasting is prescribed to you, as it was prescribed to those before you, so that you can learn self-restraint." (Qur'an 2:183).
Therefore, during the period of fast one may not only get rid of nibbling food, coffee, smoking but also of anger and excessive sexual passion. In fact, the fast not only gives rest to the stomach but also stabilizes the secretion of hormones which control our behavior.
E. Hajj (Pilgrimage to Makkah):
The moral is Prophet lbrahim 's submission and absolute surrender to God's will, the opportunity for repentance, and the social and political gathering of the Ummah depicting brotherhood and equality.
However, this can be used for programming and testing us for physical endurance, a requirement for all able men and women. The long walks, the heat, the sun, the thirst, the physical exercise, etc. is to remind us of the Day of Judgment.
We should perform Hajj when we are young and physically well rather than wait for old age. We should keep ourselves in good shape before and after the Hajj. After describing the pillars of faith as a basis for the spiritual health, let us talk about the maintenance of the physical structure in which the spirit resides.
Allah loves His creations so much that He is concerned even with what we eat and put in our body.
Our muscles, bones, lungs, liver, brain and secretions are made from the raw product we feed it. If we provide the factory with junk raw products, the factory will not produce tough bones, strong muscles, good pump (heart) and clean pipes (vessels). "O mankind: Eat of what is lawful and good on earth" (Qur'an 2: 168).
Forbidden to us are dead meat, blood and flesh of swine (see Qur'an 5:3) and intoxicants (Qur'an 5:91, 92, and 2:219).
The blood and meat of the dead could be full of germs and other harmful elements like antibodies. Pork meat is high in cholesterol, salt and may have worms, and alcohol and other intoxicants that cloud our inhibition and interfere with our normal capacity of judging good and bad.
Therefore, a person under the influence of alcohol may want to take off his dress, engage in unlawful sexual acts, become violent and abusive without even knowing what he is doing. On medical damages due to alcohol, whole books have been written.
The second component in nutrition (after permission of the lawful and probation of the unlawful) is the moderation in the lawful.
Obesity is a major American tragedy, a form of malnutrition, affecting millions of people, of all age. Ninety-nine percent of obesity is due to overeating. Allah advises as to be moderate in quantity. "But waste not by excess for God loves not the wasters" (Qur'an 7:31).
Certain types of food i.e. fruits are especially emphasized in Qur'an (36:57, 43:73, 16:67) "And from the fruits of date palm and grapes you get wholesome drink and nutrition: Behold in this is a sign for those who are wise" (Qur'an 16:67).
Fruits are low in calories, high in vitamins and minerals, and fiber and sugar is fructose and not sucrose. In a recent study by Dr. Anderson fructose has been shown to cause no rise in blood sugar and even lowers the high blood sugar of diabetics. Honey is fructose.
Allah is pure and likes purity. He is clean and likes cleanliness. Therefore, cleanliness of body and mind is stressed in Qur'an (4:43). Miswak (brushing teeth) is not a new invention of last 200 years. This was stressed as part of our daily routine by Prophet Mohammed.
He also advised us on flossing (Takhlil) as is now being advised by all the dentist. In fact, he is known to have said that if it was not a hardship for Muslims, he would have advised using Miswak before each prayer i.e. five times a day.
Cleanliness of our mind is prerequisite for total cleanliness (body and mind).
(C) The Value of exercise in maintaining health
Though we do not find much in Qur'an about specific exercise, recommendation, the Prophet's life was full of recommendations.
He, himself used to walk at a fast pace, even race with his wife, Aisha (may Allah be pleased with her).
Most importantly, he used to work with his hands whether at home, in the kitchen, or with his companions collecting wood for fire, fighting during wars etc.
It is a pity that Muslim men and women have become sedentary and, because of the excessive consumption of starches, obesity has crept into them. We should keep ourselves fit to go for Jihad and feel healthy in peacetime.
The State of disease
Many of the common chronic illnesses (i.e. coronary heart disease, hypertension, diabetes, peptic ulcer disease, obesity and depression) also have a common man-made etiology, that is rich food, too much food, too much salt, too much sugar, smoking, stress and alcoholism.
If we give up excessive salt, sugar and cholesterol from our diet, and do not drink and smoke, and stay active, it is possible that the pump (the heart) won't be rusted from inside.
What should a Muslim do when disease is confirmed?
A. Accept it as a will of God as Kaffara (expiation) for his sin, and ask him to remove the affliction. "And if God touches thee with affliction, none can remove it but He: if He touches thee with happiness He has power over all things." (Qur'an 6:17).
B. Many Muslims won't seek early medical attention, contrary to the Prophet's practice and teaching. In Christianity there is a sect believing in faith healing who have let their members die rather than go to the physician.
Usamah Bin Shareek (may Allah be pleased with him) reports: "I was with the Prophet and some Arabs came to him asking "O Messenger of Allah, do we take medicine for any disease." He said, "Yes, O you servants of Allah! Take medicine as Allah has not created a disease without creating a cure except for one. They asked which one, he replied old age'.
C. Increase your knowledge of health and disease, of medications and side effects. This knowledge is not the monopoly of doctors. You can have it and use it in preventing the illness, recognizing it early when symptoms appear, seeking early medical attention, then monitoring the course of the disease, implementing the treatment (i.e. knowledge of diet for diabetics) and recognizing side effects of the medicine.
In summary, our healthy bodies is a gift from God. We are the trustees. We should not misuse it, nor provide wrong raw products for the factory and we should keep superb maintenance of this delicate and sensitive machine, in order to enjoy it. It is the container of our soul.
