All diseases are from Allah, and the cure of them is also from Him. Invocation for diseases will help to recover from illness. It is a way to connect to Allah. It is equally important, along with medications. Allah in Quran says:

And when I am ill, it is He(Allah) who cures me.

Quran 26:80

We must seek Allah’s help together with medicines.
