Jabir reported that there happened to pass before Allah's Apostle ﷺ an ass the face of which had been cauterised, whereupon he said: Allah has cursed one who has cauterised it (on the face).

وَحَدَّثَنِي سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ، حَدَّثَنَا مَعْقِلٌ، عَنْ أَبِي الزُّبَيْرِ،
عَنْ جَابِرٍ، أَنَّ النَّبِيَّ ﷺ مَرَّ عَلَيْهِ حِمَارٌ قَدْ وُسِمَ فِي وَجْهِهِ فَقَالَ
" لَعَنَ
اللَّهُ الَّذِي وَسَمَهُ " .
