Medicine is divided into the medicine of the heart and the medicine of the body. This division is itself based upon the division of sickness. Sickness is of two types, that of the heart and that of the body.
As for the foundations of the medicine of the body, they are three, as indicated by Ibn al-Qayyim:
This medicine is known by experimentation and experience. The Prophetic medicine is the most superior form of medicine, as indicated by Ibn al-Qayyim.
As for the foundations of the medicine of the heart, they are three:
The medicine and cure of the heart takes priority over the medicine of the body and is the foundation for the medicine of the body.
This type of cure (for the heart and soul) cannot be reached except through the Prophets and Messengers through the medium of revelation. Whoever combines between the medicine of the heart and the medicine of the body will receive the bounties of this life and the next.
