"Also (forbidden are) women already married, except those whom your right hands possess. Thus has Allah ordained for you. All others are lawful, provided you seek them from your property, desiring chastity, not fornication. So with those among them whom you have enjoyed, give them their required due, but if you agree mutually after the requirement (has been determined), there is no sin on you. Surely, Allah is Ever All-Knowing, All-Wise." - Quran 4:24 (read more)

"Narrated Qatada: Anas bin Malik said, "The Prophet used to visit all his wives in a round, during the day and night and they were eleven in number." I asked Anas, "Had the Prophet the strength for it?" Anas replied, "We used to say that the Prophet was given the strength of thirty (men)." And Sa'id said on the authority of Qatada that Anas had told him about nine wives only (not eleven)." - Sahih Bukhari 1:5:268 (read more)

"The calls which urge the banning of female circumcision are call that go against Islam, because there is no clear text in the Qur’aan or Sunnah and there is no opinion of the fuqaha’ that says that female circumcision is haraam. Female circumcision is either obligatory or recommended... The words of the doctors and others are not definitive. Scientific discoveries are still opening doors every day which change our old perceptions." - Shaykh ‘Atiyah Saqar
