Azhar Nasser is no “extremist.” Islam justifies what he says here.
A hadith depicts Muhammad saying: “If a husband calls his wife to his bed [i.e. to have sexual relation] and she refuses and causes him to sleep in anger, the angels will curse her till morning” (Bukhari 4.54.460).
Another hadith attributes this to Muhammad: “By him in Whose Hand lies my life, a woman can not carry out the right of her Lord, till she carries out the right of her husband. And if he asks her to surrender herself [to him for sexual intercourse] she should not refuse him even if she is on a camel’s saddle” (Ibn Majah 1854).
The Qur’an teaches that Infidel women can be lawfully taken for sexual use (cf. its allowance for a man to take “captives of the right hand,” 4:3, 4:24, 23:1-6, 33:50, 70:30). The Qur’an says: “O Prophet, tell your wives and your daughters and the women of the believers to bring down over themselves of their outer garments. That is more suitable that they will be known and not be abused. And ever is Allah Forgiving and Merciful.” (33:59) The implication there is that if women do not cover themselves adequately with their outer garments, they may be abused, and that such abuse would be justified.
As as for wife-beating: “Men have authority over women because Allah has made the one superior to the other, and because they spend their wealth to maintain them. Good women are obedient. They guard their unseen parts because Allah has guarded them. As for those from whom you fear disobedience, admonish them and send them to beds apart and beat them.” — Qur’an 4:34
Muhammad “struck me on the chest which caused me pain, and then said: Did you think that Allah and His Apostle would deal unjustly with you?” — Aisha (Sahih Muslim 2127)
