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.
