The Quran says nothing about the veil, except for an injunction to veil the bosom, which is obvious. As for the face, Muhammad's wife Khadijeh never wore the veil, nor did the other wives of the Prophet after Khadijeh died. [...] The ulema have twisted the Quran with their hadith, always twisting it toward those in power, until the message Muhammad laid out so clearly, straight from God, has been reversed, and good Muslim women are made like slaves again, or worse.
A totally objective examination of it [the Qur'an] in the light of modern knowledge, leads us to recognize the agreement between the two, as has been already noted on repeated occasions. It makes us deem it quite unthinkable for a man of Muhammad's time to have been the author of such statements on account of the state of knowledge in his day. Such considerations are part of what gives the Qur'anic Revelation its unique place, and forces the impartial scientist to admit his inability to provide an explanation which calls solely upon materialistic reasoning."
