Dr. Hatem al-Haj, is a Muslim jurist who has stated this: The ruling on circumcision: Scholars have differed on the ruling on circumcision. They have agreed on its legitimacy for both sexes, but beyond that they have differed. Some--most famously the Shafi’ites--believe that it is obligatory for both sexes. Some believe it is obligatory for men only, and some believe it is recommended for both. At the very least it can be said that for women it is an honor, and for men it is sunnah [i.e. it is in accord with the tradition of Muhammad].
