Has it been reported from the Prophet (peace be upon him) any command or permission for his wives or daughters to undergo circumcision in an authentic hadith?

There is no known hadith in which the Prophet commanded his wives or daughters to undergo circumcision. However, it is authentically reported that he guided a woman who performed circumcisions in Medina to the praiseworthy form of circumcision, saying: "Do not cut severely, for that is more pleasing to the woman and more beloved to the husband." It is also authentically reported that "The fitra are five: circumcision, shaving the pubic hair, trimming the mustache, clipping the nails, and plucking the armpit hair," and that "When the two circumcisions meet, ghusl becomes obligatory." Female circumcision involves removing a small part of the skin that resembles a cock's comb above the urinary meatus. The Shafi'is and Hanbalis have maintained that female circumcision is obligatory, while many scholars consider it a Sunnah and a noble act. It also has medical benefits.
