The Prophet (peace and blessing be upon him) instructed us, “Seek medical treatment, for Allah has provided a cure for every illness.” (Abu Dawud)
This Hadith should be taken as encouragement to seek medical treatmentalong with making duaa, imploring Allah to cure one’s illness.
Moreover, when the Prophet was ill, he sought medical treatment. This shows that trying to overcome illness by an effectivemedicine or herb is necessary to preserve the body against the attack of germs and viruses.
Here are few of the supplications you can use for purpose of healing as mentioned in the Sunnah:
1) Allahumma rabba al-nnas adhhibi al-ba’sa ishfi anta al-sshafi la shifa’a illa shifa’ula shifa’an la yughadiru saqaman.
(O Allah, O Lord of Mankind, remove the affliction and send down cure and healing, for no one can cure but You; so cure in such a way that no trace of illness is left).
2) As’alu Allaha al-zheem rabba al-‘arshi al-azheem an yashfiyane.
(I beseech Allah, the Great, Lord of the Mighty Throne, to heal me).
3) A’udhu bi izzati Allahi wa qudratihi mimma ajidu wa uhadhiru.
(I seek refuge and protection in the august might and power of Allah from the pain and illness I am suffering from and I’m afraid of).
Furthermore, you may also repeat and meditate on some of the beautiful Names of Allah: i.e., ya rahamanu ya rahem; ya shafi,
(O the most Merciful one, O the Healer and curer)
