The mihrab is a niche in the wall facing Mecca, indicating the qibla, the direction believers should face while praying. To the right of the mihrab is the minbar, a pulpit chair to the right of the mihrab traditionally reached by three steps, dating from the Prophet Mohammed’s time. The `imam', the one who leads the prayer, delivers the `khutba', the Friday sermon, which can deal with religious, social and political subjects.
