What is the ruling on praying on carpets with raised or lowered patterns, and does the difference in thickness affect the ability of the limbs to reach the ground?

The variation in the weave of carpets and rugs does not affect the validity of prostrating on them, because they are a place where the organs of pro prostration rest on what is connected to the ground. Scholars have explicitly stated the permissibility of praying on carpets and rugs made of wool, hair, animal fur, and all other pure materials, such as mats, carpets, and woven garments.
