Many Muslims see passages in the Qur'an which, by implication, oppose FGM. they reason:
God apparently created the clitoris for the sole purpose of generating pleasure. It has no other purpose. There is no instruction in the Qur'an or in the writings of the Prophet Mohammed which require that the clitoris be surgically modified. Thus God must approve of its presence. And so, it should not be removed or reduced in size or function. The Qur'an promotes the concept of a husband and wife giving each other pleasure during sexual intercourse. For example: "It is lawful for you to go in unto your wives during the night preceding the (day's) fast: they are as a garment for you and you are as a garment for them." (2:187) "...and He has put love and mercy between you." (30:21) Mutilated genitalia reduce or eliminate a woman's pleasure during the act.
The Qur'an (An-Nisa': 119) states that Satan will try to trick humans into body modification: "And I will surely lead them astray, and arouse desires in them, and command them and they will cut the cattle's ears, and I will surely command them and they will change Allah's creation." This might be interpreted as forbidding FGM as well as tattoos, piercing and any other modification that alters the design of the human body as Allah created it. Nawal El-Saadawi, a Muslim victim of infibulation, stated:
"The importance given to virginity and an intact hymen in these societies is the reason why female circumcision still remains a very widespread practice despite a growing tendency, especially in urban Egypt, to do away with it as something outdated and harmful. Behind circumcision lies the belief that, by removing parts of girls' external genitals organs, sexual desire is minimized. This permits a female who has reached the dangerous age of puberty and adolescence to protect her virginity, and therefore her honor, with greater ease. Chastity was imposed on male attendants in the female harem by castration which turned them into inoffensive eunuchs. Similarly female circumcision is meant to preserve the chastity of young girls by reducing their desire for sexual intercourse.
