Narrated Imran ibn Husayn: 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.

Hadith Takhrij« تفرد بہ أبو داود، (تحفة الأشراف: 10845)، وقد أخرجہ: سنن الترمذی/الطب 10 (2094)، سنن ابن ماجہ/الطب 23 (3491)، مسند احمد (4/444، 446) (صحیح) »
´Imran bin Husain narrated that the Messenger of Allah (s.a.w) prohibited cauterization. He said:` "We were tested (with severe medical condition) so we were cauterized, but we did not have good results, nor was it successful for us." Another chain reports a similar narration.
Shaykh Dr. Abdur Rahman Freywai
Explanation: 1: The prohibition of cauterization for treatment is to be understood as being of a non-emphatic (tanzihi) nature, meaning that it is better not to cauterize. One opinion is also that this prohibition is specific to Imran bin Husayn (radi Allahu anhu), because it is possible that he was afflicted with such an illness in which cauterizing the body would have caused him harm rather than benefit. See the next hadith.
