Centuries ago, Allah (SWT) sent down Qur'an to mankind as a book of Guidance. Quran and its superior wisdom are definite evidence that it is the word of Allah. In addition, the Quran has many miraculous attributes proving that it is a revelation from Allah. One of these attributes is the medical Miracle of Qur’an .Qur’an has to say a lot about medicine. Holy Qur’aan has healing power for the believers. This includes healing the heart (mental or spiritual disease) and physical healing. Allah mentions honey in the Qur’an and says that it is a healing for mankind. And He mentions the principle of preserving good health and guarding against sickness. Some of the Verses which indicate that the Qur’aan is healing are:
“And We send down of the Qur’aan that which is a healing and a mercy to those who believe…” [al-Isra’ 17:82]
“O mankind! There has come to you a good advice from your Lord (i.e. the Qur’aan, enjoining all that is good and forbidding all that is evil), and a healing for that (disease of ignorance, doubt, hypocrisy and differences) which is in your hearts” [Yoonus 10:57]
The Qur’aan is the complete healing for all mental, spiritual and physical diseases, all diseases of this world and the Hereafter. But not everyone is guided to use it for the purpose of healing. If the sick person uses the Qur’aan for healing in the proper way, and applies it to his disease with sincerity, faith, complete acceptance and firm conviction, fulfilling all its conditions, then no disease can resist it.
The Qur’aan contains the treatment for hearts and souls, and as such it is a means of expelling all sicknesses from the body. In this regard the Qur’an is a healing and a remedy for many diseases. Honey is mentioned in the Qur’an, and that it is a healing for mankind. Allah says:
“There comes forth from their [bees’] bellies, a drink of varying colour wherein is healing for men” [al-Nahl 16:69]
QUR’AN mentions the principle of maintaining good health
Ibn al-Qayyim said The basic principles of medicine are three: prevention, maintaining good health, and removing harmful substances from the body. Allah has mentioned them all together, to His Prophet and his Ummah in three places in His Book.
1. Prevention: He prevented the sick person from using water lest it harm him. Allah allowed the sick person to do Tayammum to protect him, just as He permitted it to the one who has no water, as He says: “And if you are ill, or on a journey, or one of you comes after answering the call of nature, or you have been in contact with women and you find no water, perform Tayammum with clean earth and rub therewith your faces and hands (Tayammum)” [al-Nisa’ 4:42]
2. Maintenance of Good health: Allah says concerning the maintenance of good health: “and whoever is ill or on a journey, the same number [of days which one did not observe Sawm (fasts) must be made up] from other days” [al-Baqarah 2:185] The traveler is allowed to break his fast during Ramadaan, to protect his health lest the combination of fasting and the difficulties of travel weakens him and affects his health.
3. Removal of Harmful Things: Allaah said concerning the removal of harmful things by shaving the head of the person in ihraam (for Hajj or ‘Umrah): “And whosoever of you is ill or has an ailment in his scalp (necessitating shaving), he must pay a Fidyah (ransom) of either observing Sawm (fasts) (three days) or giving Sadaqah (charity — feeding six poor persons) or offering sacrifice (one sheep)” [al-Baqarah 2:196]
So if a person has an ailment in his scalp when he is in ihraam, he is permitted to shave his head and remove the harmful thing or the bad substance that is causing lice to develop – as happened to Ka’b ibn ‘Ajrah – or if it is causing sickness to develop.
These three matters are the basic principles of medicine. An example of each one is mentioned in order to point out the blessing of Allaah to His slaves in preventing sickness, protecting their health and removing harmful substances from them, as a mercy and kindness towards His slaves, for He is the Most Kind, Most Merciful.

Ibn al-Qayyim said: On one occasion I discussed this with one of the chief doctors of Egypt, and he said: By Allaah if I had to travel to the west to obtain these benefits that would not be too much – or words to that effect. [Ighaathat al-Lahfaan, 1/25]
