"Narrated Abdullah ibn AbuDhubab: Iyas ibn Abdullah ibn AbuDhubab reported the Apostle of Allah (peace be upon him) as saying: Do not beat Allah's handmaidens, but when Umar came to the Apostle of Allah (peace be upon him) and said: Women have become emboldened towards their husbands, he (the Prophet) gave permission to beat them." - Sunan Abu Dawud 11:2141 (read more)

"Circumcision [of females] is not an inherited custom as some people claim, rather it is prescribed in Islam and the scholars are unanimously agreed that it is prescribed. Not a single Muslim scholar – as far as we know – has said that circumcision is not prescribed. Their evidence is to be found in the saheeh ahaadeeth of the Prophet (peace and blessings of Allaah be upon him), which prove that it is prescribed... Thus it is clear that the fuqaha’ of Islam are agreed that circumcision is prescribed for both males and females, and in fact the majority of them are of the view that it is obligatory for both. No one said that it is not prescribed or that it is makrooh or haraam." - Islam Q&A
