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

Al-Husayn ibn Muhammad from Mu‘alla ibn Muhammad from Muhammad ibn Abdullah al-Wasiti from Qasim al-Sayqal, who said: I wrote to (Imam) al-Ridha عليه السلام, peace be upon him, saying: “I work in making scabbards for swords from the skins of dead donkeys, and these skins touch my clothes, can I pray in them?” Imam عليه السلام wrote back to me: "Designate a specific garment for your prayer." Then I wrote to Abu Ja‘far عليه السلام, peace be upon him, saying: “I had written to your father عليه السلام, peace be upon him, about such-and-such, and it was difficult for me, so I began to make them from the skins of wild donkeys that had been slaughtered according to proper Islamic method (dhakiyyah).” Imam عليه السلام wrote back to me: "All righteous deeds are accompanied by patience, may Allah سبحانه وتعالى have mercy on you. If what you work with is from wild animals properly slaughtered (dhakiyyah), then there is no harm."
