Harun bin 'Abdullah al-Hamal هارون بن عبد الله بن مروان الحمال · Medicine (Kitab Al-Tibb)

I came to the Prophet (ﷺ) and his Companions were sitting as if they had birds on their heads. I saluted and sat down. The desert Arabs then came from here and there. They asked: Messenger of Allah, should we make use of medical treatment? He replied: Make use of medical treatment, for Allah has not made a disease without appointing a remedy for it, with the exception of one disease, namely old age.

I heard the Messenger of Allah (ﷺ) say: If I drink an antidote, or tie an amulet, or compose poetry, I am the type who does not care what he does. Abu Dawud said: THis was peculiar to the Prophet (ﷺ), but some people have allowed to use it, i.e. antidote.
