Prayer rugs: about

The prayer rug was evidently invented for the pur­pose of providing the worshippers with one absolutely clean place on which to offer prayers.

It is not lawful for a Moslem to pray on any place not perfectly clean, and unless each one has his own special rug he is not certain that the spot has not been polluted.

With regard to the purity of the place of prayer Moham­medans are especially careful when making their pil­grimages, the rugs which they take with them having been preserved from pollution by being rolled up until the journey is begun, or until the hour of prayer arrives.

It does not matter to these followers of Mohammed how unclean a rug that is on the floor may be, because over it they place the prayer rug when their devotions begin.
