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

From him, from Al-‘Amraki, from Ali ibn Ja‘far, from his brother (Imam) Musa عليه السلام, peace be upon him, who said: I asked Him عليه السلام about a man, does it suffice for him to gather the two ends of his cloak over his left shoulder? Imam عليه السلام said: "It is not appropriate to gather them over the left shoulder; rather, gather them over your right shoulder, or leave them." He (narrator) said: “And I asked Imam عليه السلام about reed mats (al-bawari’) that have been soiled with urine, does prayer on them suffice if they have dried without being washed?” Imam عليه السلام said: "Yes, there is no problem." He (narrator) said: “And I asked Imam عليه السلام about praying on the reed mats of Christians and Jews, upon which they sit in their homes, does it suffice?” Imam عليه السلام said: "Do not pray on them." And I asked Imam عليه السلام about the sword, does it take the place of the cloak, such that one may lead the people in prayer wearing only the sword? Imam عليه السلام said: "It is not appropriate to lead people in prayer while wearing only the sword, except in battle."
