Does the Holy Quran still contain medical facts that have not yet been discovered, especially concerning the control of fatal diseases, or is what has been deduced all that it contains?

The Holy Quran is not a book of medicine; rather, it is a book of guidance. Allah Almighty revealed it to challenge eloquent speakers with its eloquence and the power of its meanings. Nevertheless, the Quran is a healing and a mercy for believers, encompassing the healing of hearts and bodies. It serves as a guide to medicine for every illness for those whom Allah has blessed with understanding of His Book. The Quran also mentions some verses that describe the composition of the human body and natural phenomena, and principles of health preservation such as diet, maintaining good health, and expelling harmful substances, as well as honey being a healing for people. It is a cure for souls and spirits, and whoever is spiritually sound through it will have ailments and diseases expelled from their body.
