Sahih al-Bukhari 5943
Narrated Ibn Mas`ud:
Allah has cursed those women who practise tattooing or get it done for themselves, and those who 
remove hair from their faces, and those who create spaces between their teeth artificially to look 
beautiful, such ladies as change the features created by Allah. Why then shall I not curse those whom 
Allah's Messenger (ﷺ) has cursed and who are cursed in Allah's Book too?
حَدَّثَنِي مُحَمَّدُ بْنُ مُقَاتِلٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنِ ابْنِ مَسْعُودٍ ـ رضى الله عنه ـ قَالَ لَعَنَ اللَّهُ الْوَاشِمَاتِ، وَالْمُسْتَوْشِمَاتِ، وَالْمُتَنَمِّصَاتِ وَالْمُتَفَلِّجَاتِ لِلْحُسْنِ، الْمُغَيِّرَاتِ خَلْقَ اللَّهِ، مَا لِي لاَ أَلْعَنُ مَنْ لَعَنَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم وَهْوَ فِي كِتَابِ اللَّهِ‏.‏
