Do you mean for FGM? FGM is an ancient practice, In a documentary I heard one elderly West African lady say the practice was "As old as Africa"; it was made illegal in Nigeria in the 1950s but still happens in remote places, usually performed by grandmothers. It is done regardless of religion,whether they're Christian, Muslim or adhere to one of the older religions.
It happens in predominantly Muslim countries such as Ethiopia and even Egypt but has nothing to do with the Qu'ran.
The Somali government issued a fatwa against the practice not that long ago (but still happens).
The Saudis are trying to stop it, it's not common practice but it happens in Southern regions bordering on Yemen.

Some Christian communities from Egypt, Kenya, Nigeria and Tanzania consider FGM to be a religious requirement;they're wrong but it's a custom firmly ingrained in their culture.
There's no religion that insists on female genital mutilation, indeed some are firmly against it. Nevertheless it happens and has happened for generations amongst people from various parts of the world.
(We don't have to touch on FGM performed in the USA and here, probably other places, on women like ourselves who were judged to be morally lax or in moral danger, that's a different story.)
A very good book to read is Alice Walker's novel, 'Possessing the Secret of Joy'. It's well researched and informative on the subject of female circumcision.
Male circumcision is a religious practice for Jews and Muslims but happens for other, non-medical, reasons too.
