Chapter on What is Permissible and Impermissible to Pray in - of Clothing and Place

Sa‘d, from Ahmad ibn Al-Hasan, from ‘Amr ibn Sa‘id, from Musaddiq ibn Sadaqah, from ‘Ammar ibn Musa Al-Sabati, said: I asked Abu Abdillah عليه السلام, peace be upon him, about a ‘bariyyah’ (a mat) whose reeds were moistened with impure water, does it suffice to pray on it? Imam عليه السلام said: "If it has dried, then there is no problem in praying on it."
