Every human desires good health and wellness. Islam promotes healthy living and taking care of one's health by adopting a healthy lifestyle.
Good health is indeed a great blessing bestowed by Allah Ta'ala upon mankind. Islamic teachings are a guide to every aspect of a Muslim's life. Maintaining a healthy lifestyle is essentially prescribed as a means to worship Allah. A healthy Muslim who is strong in body and mind can fulfil the commands of Allah and the teachings prescribed by our beloved Nabi -
The Human Body
The human body is a composition of the physical and spiritual dimension. Our bodies need oxygen, water and food to survive. At the same time what we consume impacts on our health and general wellbeing.
Keeping our bodies in good physical condition also means we can lead a healthier life.
The body has a right
Nabi 11said, "The body has a right over you." (Bukhari)
Allah has bestowed to us this body as an amanah (trust). Hence, we ought to look after it to the best of our ability.
Nourishment of good and wholesome food is essential, at the same time, it is necessary to abstain from haram (unlawful) food, drink and all substances that may cause harm to the body and mind.
It is advisable to seek medical help in order to nurture and care for the body and restore good health. Ultimately, Allah Ta'alaAlone is the curer of all ills. Nabi advised, "Allah sends down both the sickness and the cure; and He has assigned for every sickness a remedy, so seek treatment, but not by prohibited means." (Abu Dawood)
Prevention is better than cure
Islam is foremost in preventative methods of ills, misfortunes and sicknesses. Nabi 11 said, "Whatever causes harm to people should be removed ."(Ahmed)
This can refer to many things, inter alia, polluted air, toxic food, unclean water, etc. Allah says in
Surah 4 Verse 29, "And do not kill yourselves (nor kill one another). Surely, Allah is Most Merciful to you."
Hence, all things that may cause harm to you or the environment should be avoided at all costs. The Shariah admonishes Muslims to abstain from all things that are harmful to health.
Apart from seeking medical help, the verses of the Noble Quran contain great healing powers. Allah Ta'ala elucidates, "And we send down from the Quran that which is a healing and a mercy to those who believe" (Surah 17, Verse 82)
As the saying goes, "A man is what he eats" hence, Allah Ta'ala has prescribed the best and made unlawful for us to consume intoxicants like alcohol, etc.
The intake of prohibited food and drink is a principle cause of a man leading to vice.
Further, while one consumes Halaal (permitted) food, the acquisition of food must also be through rightful and lawful earnings.
Indeed, there are great blessings and benefits in following the Sunnah of our Nabi - The Sunnah is the best way of life fora Muslim.
For example, Islam has placed great emphasis on purification and cleanliness of the body and the mind.
Allah Ta'ala says in the Noble Quran, "In it are men who love to clean and to purify themselves. And Allah loves those who make themselves clean and pure." (Surah 9, Verse 108)
One cannot neglect one's spiritual well-being for a healthy life. Personal spiritual growth and reformation is equally important, in fact greater than looking after the physical body.
Hazrat Abu Hurayrah narrates that Rasulullah iji was asked,"What enters a person into Jannah? It is Taqwa (i.e. fear of Allah) and good character and He iji was asked what generally takes people to Jahannam? He said, the mouth and private parts." (Tirmizi)
Remember Allah Ta'ala is the Greatest
Hazrat Abu Hurayrah narrates that Rasulullah iji said, "Allah Ta'ala says that when My servant remembers Me and moves his lips for My Dhikr, then I am with him (i.e. I help him, grant him ability and have mercy and consideration for him)." (Bukhari -Ta'leeqan)
