“If it is anything (that heals), then
it is in cupping, black cumin, a gulp of honey or branding with fire
(cauterization) that suits the ailment, but I don’t like to be cauterized.”
Recorded by Ibn Jarir and Al-Hakim in Al-Mustadrak. He considered it to be
authentic, vol. 4, hadith no.209, and the text has authentic books.
