Sahih Bukhari Volume 7, Book 77, Hadith 5950

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، عَنْ سُفْيَانَ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ لَعَنَ اللَّهُ الْوَاشِمَاتِ وَالْمُسْتَوْشِمَاتِ، وَالْمُتَنَمِّصَاتِ وَالْمُتَفَلِّجَاتِ لِلْحُسْنِ، الْمُغَيِّرَاتِ خَلْقَ اللَّهِ‏.‏ مَا لِي لاَ أَلْعَنُ مَنْ لَعَنَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَهْوَ فِي كِتَابِ اللَّهِ‏؟

Narrated By '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 Apostle has cursed and that is in Allah's Book?
