The "qiblah wall" is usually at the other side of the entrance to the prayer hall. This wall is specially decorated. In a properly sited mosque, it will be set perpendicular to a line leading to Mecca. People pray in rows parallel to the "qiblah" wall. They arrange themselves so they face Mecca. In the "qiblah" wall, usually at its center, is the "mihrab", a niche or depression showing the direction of Mecca. The "mihrab" serves as the place where the imam leads the five daily prayers.
