Prayer mat

A prayer rug or prayer mat (Arabic: سجادة‎‎ sajjāda pl. سجاجيد sajājīd, or musallah; Turkish: seccade or namazlık; Persian: جانماز‎‎, Urdu: جانماز‎ jānamāz, Bengali: জায়নামাজ jaênamaj) is a piece of fabric, sometimes a pile carpet, used by Muslims, placed between the ground and the worshipper for cleanliness during the various positions of Islamic prayer. These involve prostration and sitting on the ground. A Muslim must perform wudu (ablution) before prayer, and must pray in a clean place. Many new prayer mats are manufactured by weavers in a factory. The design of a prayer mat is based on the village it came from and its weaver.

When praying, a niche, representing the mihrab of a mosque, at the top of the mat must be pointed to the Islamic center for prayer, Mecca. All Muslims are required to know the qibla or direction towards Mecca from their home or where they are while traveling.

The prayer rug has a very strong symbolic meaning and traditionally taken care of in a holy manner. It is disrespectful for one to place a prayer mat in a dirty location (as Muslims have to be clean to show their respect to God) or throw it around in a disrespectful manner. The prayer mat is traditionally woven with a rectangular design, typically made asymmetrical by the niche at the head end. Within the rectangle one usually finds images of Islamic symbols and architecture. In some cultures decorations not only are important but also have a deep sense of value in the design of the prayer rug.
