They allow non-Muslims to tour the mosque during certain times of the day. So Ashley and I went yesterday morning (Monday), and we were able to take a few photos inside. The lighting was not so good, so have some compassion if things are blurry or dark.
The picture above is of the floor where men come to pray. Particularly on Fridays this area can be pretty close to full. The ropes set off the area where the King processes in to pray. At the end of this area is a niche that points toward Mecca (it looks kind of like a doorway in the center of the photo above), and to the right is a podium-like stand where an imam delivers the Friday-sermon. The picture below is of the terrace area where women pray. It's difficult to see in this photo, but there are slots in the walls of the terrace for the women to see through.
Below is a picture of the fountains used for washing, which is required of devotees for purification before prayer. There is a separate area for men and women, but this area was only used for tours (which, of course, are not conducted during prayer times). The purification process includes washing hands, arms, and the face three times. If I understood correctly, they also wash their forehead and behind their ears once (as opposed to three times).
Also, near the mosque is a theological school, but currently it is not in use. It is designed in similarly ornate patterns. This school forms a kind of U in the beginning of the vast courtyard area that you can see in the first picture of this post.
