"Men are overseers over women, by reason of that wherewith Allah hath made one of them excel over another, and by reason of that which they expend of their substance. Wherefore righteous women are obedient, and are watchers in husbands absence by the aid and protection of Allah. And those wives whose refractoriness ye fear, exhort them, and avoid them in beds, and beat them; but if they obey you, seek not a way against them; verily Allah is ever Lofty, Grand." - Quran 4:34 (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 defeatists among the Muslims come out to defend Islam, and they want to disavow Islam of this so-called lie, so they deny that Islam was spread by the sword, and they say that jihad is not prescribed in Islam, except in the case of self-defence. There is no such thing in Islam as taking the initiative in fighting in their view. This goes against what the Muslim scholars have stated, let alone the fact that it goes against the Qur’aan and Sunnah." - Sheikh Muhammed Salih Al-Munajjid
