Final answer:
A mihrab is a niche in the wall of a mosque that indicates the qibla, the direction towards Mecca, which is important for Muslim prayer. It is often richly decorated and situated on the qibla wall, adjacent to the minbar, the pulpit used during sermons.
Step-by-step explanation:
In Islamic Architecture, the niche in the wall of a mosque that indicates the direction to Mecca is called a mihrab. The direction of Mecca is referred to as the qibla, and the wall where the mihrab is located is called the qibla wall. This wall is often the most ornately decorated area in a mosque to emphasize its importance, as it directs worshippers towards Mecca during their prayers. Next to the mihrab, you may also find a minbar, which is a pulpit where the Imam stands to deliver sermons. It is usually found on the qibla wall, which is the wall that faces Mecca.
The mihrab's significance goes beyond its practical use; it embodies both religious and architectural importance. It is typically characterized by an ornate arch and is sometimes surrounded by lavish decorations of calligraphy and geometric patterns. The mihrab varies in size and design but always serves as the focal point in a mosque's prayer hall, helping the faithful to orient themselves during prayer.
