Cosmetic surgery is permissible to correct deformities or to return a person’s appearance back to normal after an accident. It is lawful for a person to make amendments to appearance when some natural defect exists or some disfiguring accident has occurred.
It is not allowed merely to change a person’s normal appearance or to make that person appear more attractive according to some notion of beauty. In the Qur’ân, Allah says that Satan will lead people astray and that one of the ways he will do this is to get them to alter Allah’s creation.
Allah says: “Allah cursed him and he (Satan) said: ‘I will take from your servant a portion determined. I will mislead them and create within them false desires. I will order them to slit the ears of cattle and to change Allah’s creation.’ Whoever takes Satan as a friend instead of Allah has surely suffered a great loss.” [Sûrah al-Nisâ’: 118-119]
