I have several times read in, probably, right wing, media that the motivation for the Muslim veil (and general requirement that women must not "show skin") is sexist towards men. IIRC, the reasoning usually goes something like this: there are suras, verses or sunnahs (or other sources of similar importance) that suggest that women need to cover up in general, and with a veil in particular, because otherwise men won't be able to control their lust.
Is this true? In what sources is this prescribed? Are there any "counter-claims"?
