"Abu Huraira reported Allah's Messenger (may peace be upon him) as saying: The last hour would not come unless the Muslims will fight against the Jews and the Muslims would kill them until the Jews would hide themselves behind a stone or a tree and a stone or a tree would say: Muslim, or the servant of Allah, there is a Jew behind me; come and kill him; but the tree Gharqad would not say, for it is the tree of the Jews." - Sahih Muslim 41:6985 (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
