"Permitted to you, on the night of the fasts, is the approach to your wives. They are your garments and ye are their garments. Allah knoweth what ye used to do secretly among yourselves; but He turned to you and forgave you; so now associate with them, and seek what Allah Hath ordained for you, and eat and drink, until the white thread of dawn appear to you distinct from its black thread; then complete your fast Till the night appears; but do not associate with your wives while ye are in retreat in the mosques. Those are Limits (set by) Allah: Approach not nigh thereto. Thus doth Allah make clear His Signs to men: that they may learn self-restraint." - Quran 2:187 (read more)

"Narrated Atiyyah al-Qurazi: I was among the captives of Banu Qurayzah. They (the Companions) examined us, and those who had begun to grow hair (pubes) were killed, and those who had not were not killed. I was among those who had not grown hair." - Sunan Abu Dawud 38:4390 (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
