From Sahih Bukhari (Hadith 5948):
Narrated `Abdullah:Allah has cursed those women who practise tattooing and those who get it done for themselves, and those who remove hair from their faces, and those who artificially create spaces between their teeth to look beautiful, such women as alter the features created by Allah. Why should I not then curse those whom Allah's Messenger (ﷺ) has cursed and that is in Allah's Book?
