Prophetic Medicine
It is from the great blessing of Allah (subḥānahū wa ta‘ālā) upon us that He has laid down a cure for every disease, except death. The following are some examples of the medicines the Prophet ﷺ prescribed for different illnesses:
Black Seed
The Messenger of Allah ﷺ said: “Indeed, in black seed is a cure for all diseases except sām (death).” (Muslim)
Zamzam
The Messenger of Allah ﷺ said: “The water of zamzam is for whatever it is drunk for.” (Ibn Mājah)
The Messenger of Allah ﷺ said: “The best water upon the surface of the earth is zamzam water. It is a nourishing food and a cure for illnesses.” (Ṭabarānī)
‘Urwah b. Zubayr (raḍiy Allāhu ‘anhumā) reported that ‘Ā’ishah (raḍiy Allāhu ‘anhā) used to bring back zamzam water with her from Makkah, and she used to say: “The Messenger of Allah ﷺ used to bring back zamzam water in water skins and jars. He would pour it over the sick and make them drink it.” (Tirmidhī)
Olive Oil
The Messenger of Allah ﷺ said: “Use olive oil in eating and for applying (on the body), for it is from a blessed tree.” (Tirmidhī)
Honey
“There emerges from their bellies (honey bees) a drink, varying in colours, in which there is healing for people.” (16:69)
Talbīnah (Barley Broth)
‘Ā’ishah (raḍiy Allāhu ‘anhā) used to recommend talbīnah for the sick and for the bereaved. She used to say: “I heard the Messenger of Allah ﷺ saying: ‘Talbīnah brings comfort to a sick person’s heart, and relieves some of their sorrow and grief.’” (Bukhārī)
‘Ajwah Dates
The Messenger of Allah ﷺ said: “Whoever eats seven ‘ajwah dates in the morning, neither magic nor poison will harm him that day.” (Bukhārī)
Indian Incense and Sea Incense (al-Qust al-Hindī and al-Qust al-Baḥrī)
The Messenger of Allah ﷺ said: “Treat with the Indian incense, for it heals seven diseases; it is to be sniffed by one experiencing throat trouble, and to be put into one side of the mouth of one suffering from pleurisy.” (Bukhārī)
The Messenger of Allah ﷺ said: “The best medicines you may treat yourselves with are cupping and sea incense.” (Bukhārī)
Cupping
The Messenger of Allah ﷺ said: “Jibrīl (‘alayhis-salām) informed me that cupping is the most beneficial medicine for the people.” (Ḥākim)
Cow’s Milk (Raw)
The Messenger of Allah ﷺ said: “Allah has not created a sickness but that He has created a cure for it, except for old age. So drink from the milk of cows, because they eat from all sorts of plants.” (Nasā’ī)
Senna
The Messenger of Allah ﷺ said: “Make good use of senna and sannūt (honey), for indeed there is a cure in both of them for every disease except sām.” He was asked: “O Messenger of Allah, what is sām?” He ﷺ replied: “Death.” (Ibn Mājah)
P.S. Please consult a practitioner before using some of the above for specific ailments.
Prevention is Better than Cure
The Messenger of Allah ﷺ said: “No man fills a container worse than his stomach. A few morsels that keep his back upright are sufficient for him. If he has to, then he should keep one third for food, one third for drink and one third for his breathing.” (Tirmidhī)
ِAllah reminds us: “O mankind, eat from whatever is on earth [that is] lawful (ḥalāl) and wholesome (ṭayyib) and do not follow the footsteps of Shayṭān. Indeed, he is to you a clear enemy. (2:168)
