Ibn Mas'ud (may Allah be pleased with him) said:

 لعن الله الواشمات والمستوشمات والمتنمصات والمتفلجات بالحسن، المغيرات خلق الله‏!‏ فقالت له امرأة في ذلك فقال‏:‏ وما لي لا ألعن من لعنه رسول الله صلى الله عليه وسلم وهو في كتاب الله‏؟‏‏!‏ قال الله تعالى‏:‏ ‏{‏وما آتاكم الرسول فخذوه وما نهاكم عنه فانتهوا‏}‏

Allah has cursed those women who practise tattooing and those women who have themselves tattooed, and those women who get their hair removed from their eyebrows and faces (except the beard and the mustache), and those who make artificial spaces between their teeth for beauty, whereby they change Allah's creation. A woman started to argue with him, saying: "What is all this?" He replied: "Why should I not curse those whom the Messenger of Allah (peace be upon him) cursed and who are cursed in Allah's Book? Allah, the Exalted, has said in His Book: "And whatsoever the Messenger (Muhammad (P)) gives you, take it; and whatsoever he forbids you, abstain (from it)." (59:7) [Al-Bukhari and Muslim].
