Judge Neil Davey QC said: “When you made her swear on the holy book you knew perfectly well that what you were doing was wrong.”

But that is not certain. Neil Davey assumes that the Qur’an forbids this sort of behavior, but he likely hasn’t read it.

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.

One survivor of a Muslim rape gang in the UK said that her rapists would quote Quran to her, and believed their actions justified by Islam.
