Jami` at-Tirmidhi, Book 28, Hadith 2186 (In-Book) ⓘ
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."
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الْكَىِّ . قَالَ فَابْتُلِينَا فَاكْتَوَيْنَا فَمَا أَفْلَحْنَا وَلاَ أَنْجَحْنَا . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
