If Muslims were the precursors of modern medicine it is because of their attachment to the texts of the Koran and the Sunnah, and this is what Imam As-Shafi'i explains when he says: "Science is of two types: the science of Fiqh for religion, and the science of medicine for the body, anything else is only discussion of assembly". He also says: "Do not live in a country where you do not find a scholar who answers you about your religion, and a doctor who informs you about the state of your body".

In Islam, the health of the body is a basic necessity in the life of people, which is why the Muslim is called to give importance to his own health but also to the health of the whole society, this so that the Muslim society remains strong. This can only be achieved through the teachings of the Messenger of Allah (salallahou alayhi wa salam) because health encompasses both the health of the body and the health of the heart, and only the science of the Prophets which is revelation combines these two things perfectly.

The medicine of the Prophet is not similar to that of doctors, because his medicine is certain, formal and divine, it emanates from revelation, from prophecy and from the perfection of reason. Prophetic medicine is suitable for good bodies, just as the Quran is suitable for good souls and living hearts.
