Undecorated octagonal clay prayer stone made from the sacred earth of Karbala.
This tablet is made from a mixture of clay and soil, it is called a turbah in Arabic (تربة) or a mohr in Persian (مهر). Turbah are used by Shia Muslims during their daily prayers (Salat). The turbah is placed on the ground in front of the person praying who then leans forward and touches it with his or her head. The act of prostration (Sajda) upon the earth’s soil is of great significance in Muslim prayer. The use of turbah can be understood as an adaptation of this concept to prayer in places where the earth is covered with a floor. For Shia Muslims the most favoured soil is that of Karbala, the site of the martyrdom of Imam Husayn ibn Ali; however soil from anywhere may be used.
