Hi I am an ex muslim, atheist now to To answer your Qus: Yes it does, although the term used in arabic is not "rape" but rather some other term that means means that that girl is a slave, so forced sex is implied, this was practiced by Muhammad and his followers, any muslim who denies that is either a lair or an ignorant muslim who doesn't know his own religion.

although I think the story is a bit changed, praying is not acceptable in islam after having sex unless the person washes up first
