"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)

He said, "This is the deficiency in her religion." - Sahih Bukhari 1:6:301 (read more)

"In this verse [5:51] Allaah tells us that whoever takes the Jews and Christians as friends is one of them because of his taking them as friends. Elsewhere Allaah states that taking them as friends incurs the wrath of Allaah and His eternal punishment, and that if the one who takes them as friends was a true believer he would not have taken them as friends." - Shaykh al-Shanqeeti
