"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)

"And he [Muhammad] had their hands and feet cut off. Then he ordered for nails which were heated and passed over their eyes, and whey were left in the Harra (i.e. rocky land in Medina). They asked for water, and nobody provided them with water till they died (Abu Qilaba, a sub-narrator said, 'They committed murder and theft and fought against Allah and His Apostle, and spread evil in the land.')" - Sahih Bukhari 1:3:63 (read more)

"Other scholars said Q. 2:256 has not been abrogated, but it had a special application. It was revealed concerning the people of the Book [the Jews and the Christians]; they can not be compelled to embrace Islam if they pay the Jizia (that is head tax on free non-Muslims under Muslim rule). It is only the idol worshippers who are compelled to embrace Islam and upon them Q. 9:73 applies ['O Prophet, struggle with the unbelievers and hypocrites, and be thou harsh with them.']. This is the opinion of Ibn 'Abbas which is the best opinion due to the authenticity of its chain of authority." - Al-Nahas
