This is a prayer rug, also called a prayer mat. Purpose: Muslims use it to provide a clean space for prayer. Design: The arch-shaped design at one end is called a mihrab, which indicates the direction of Mecca, the direction Muslims face when praying. Material: Prayer rugs can be made of various materials, including wool, silk, or synthetic fibers. Usage: The worshipper places the rug between themselves and the ground during prayer.
