Tarek Fatah Wants Muslim Leaders to Denounce Boko Haram's Kidnapping Shenanigans

He writes:

Both the exegesis of the Qur’an and reading of the Hadith literature speak of sex slavery of non-Muslim female POWs both during and after the life of Prophet Mohammed. 

Instead of being courageous and saying while such commandments and permissions may have been valid in the seventh century, they are no longer applicable in the era of the nation-state and human rights, leaders of my community choose doublespeak.

A question for Mr. Fatah: when, exactly, were these commandments and permissions invalidated, and by whose authority were they deemed "no longer applicable"? I thought everything in the Qur'an, a supposedly perfect book about the man Muslims believe to be the most perfect human being who has ever lived, is as valid today as was back in the 7th C, and, indeed, is valid for all time.

Could it perhaps be Mr. Fatah who is engaging in a bit of doublespeak here?
