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. (Using translation from Abū Dāʾūd 3865)

«نَهَى رَسُولُ اللهِ ﷺ عَنِ الْكَيِّ فَاكْتَوَيْتُ فَمَا أَفْلَحْنَا وَلَا أَنْجَحْنَا»
