Ten places in which not to pray

"Ten places should not be prayed in: where there is mud, where there is water, in baths, in the middle of the path, among anthills, where camels come to rest, in water courses, in salty land, on snow, and in the Valley of Ḍajnān." The compiler of this book- may God be pleased with him- comments on this tradition: These are places a person should not pray insofar as they can avoid doing so. In a situation where they are in a place of water or mud and are forced to pray there, they pray by gesturing, with their bowing being lower than their prostration. As for pathways, there is no issue in praying on the sides of the street between the horses, but it is not permissible to pray in the way of traffic. As for baths, it is never permissible to pray inside them, but there is no issue if one prays in the changeroom of a bath because it is not in the bath itself. As for among anthills, it is not possible to pray there due to the many ants which would crawl on the one praying, subsequently disturbing and busying them with something other than prayer. As for where camels come to rest, it is not permissible unless one fears losing their possessions; it would be permissible in that case. There is no issue with praying in a sheep pen. As for the watercourse, it is impermissible to pray in it because one does not know if the water will begin to run while they are praying. As for salty land, no prophet or legatee ever prayed in such land. Anyone else may without issue if they pound flat the place where their forehead will prostrate. As for in snow, when a person is forced to pray on it, then they pound flat the place where their forehead will prostrate. As for the Valley of Ḍajnān and all other valleys, it is not permissible to pray in them, for they are the refuges of snakes and devils.
