10-21 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted Ahmad ibn Aba Abdullah al-Barqy, on the authority of his father, on the authority of Abdullah ibn al-Fazl, on the authority of Aba Abdullah as-Sadiq (MGB),

“You should not pray in ten places as follows: in mud; water; the bath; the middle of the road; ants’ nests; camel way-station; water streams; salty lands; in snow and in Zajnan.The compiler of the book - may God be pleased with him - said, “If one can say his prayer in another place, he should not say it in these places. However, if one is stuck in water or mud and is worried that his prayer may get too late, he can say his prayers in water and mud and just point with his head instead of bowing down and bend it down more instead of prostration. It doesn’t matter if one says his prayers on the side of the road, but he should not do so where there is traffic. One should not say his prayers in the bath. However, he can say it in the dressing room. One should never say his prayers on the ants’ nest, since then the ants will interfere with his prayer. One should not say his prayers in the camel way-station, unless he is worried that thieves might steal his belongings that are being carried by the camels. It is okay to pray in the sheep stable. One should never pray where the water may flow, since then he might get drowned. The restriction of praying in the salty land applies only to the Prophet and the Divine Leaders. If a normal person clears the place where he wants to prostrate by seriously banging on it so that there is a clean place to put his forehead on, then he can pray there. One should not pray in places like Zajnan which is located near Mecca and other similar locations, since there are snakes and other evils there.”
