no, islam does not in
anyway state that females must circumcise. the circumcision
of females was a practice in parts of africa and the middle east
before they became muslims. it was a cultural thing that got mixed
with islam...it so happened that as the people in the middle east
spread islam, they wrongly packaged the culture with islam and
spread it as an islamic practice. Hence it was perceived to been
islamic.
often in rural areas especially, the circumcision causes health
problems even up to adulthood. during childbirth it can be
problematic as well.
in fact, on the basis of potential health problems, islamically
speaking, it is discouraged..
