The Prophet (ﷺ) forbade to cauterise; we cauterised but they (cauterisation) did not benefit us, nor proved useful for us. Abu Dawud said: He used to hear the salutation of the angels: When he cauterized, it stopped. When he abandoned, it returned to him.
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.
Wa'il said: Tariq ibn Suwayd or Suwayd ibn Tariq asked the Prophet (ﷺ) about wine, but he forbade it. He again asked him, but he forbade him. He said to him: Prophet of Allah, it is a medicine. The Prophet (ﷺ) said: No it is a disease.
The Prophet (ﷺ) said: Allah has sent down both the disease and the cure, and He has appointed a cure for every disease, so treat yourselves medically, but use nothing unlawful.
