An Islamic prayer mat, also known as a Janamaz, Mussallah, or Salaat rug, is a piece of fabric or material used by Muslims during their daily prayers (Salah). These prayer mats often have specific designs or markings indicating the direction of Mecca (qibla) and may feature various patterns or embellishments.

The term "hair on leather" in the context of a prayer mat likely refers to a specific type of material used in its construction. It suggests that the prayer mat is made from leather with natural animal hair still attached to it, which can give it a unique texture and appearance. This type of prayer mat might be preferred by some individuals for its traditional or aesthetic qualities.

Islamic prayer mats come in various materials, styles, and designs, catering to personal preferences and cultural traditions. They serve as a clean and designated surface for Muslims to perform their prayers, ensuring that they are performed in a state of cleanliness and respect.
