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

Ahmad ibn Muhammad, from Ahmad ibn Muhammad ibn Abi Nasr, said: I said to Abu Al-Hasan عليه السلام: “We were in Al-Bayda’ at the end of the night, so I performed wudu and used a tooth-stick (siwak), and I was about to pray, then something entered my heart (caused doubt), is it permissible to pray in Al-Bayda’ while in the litter (on the camel)?” Imam عليه السلام said: "Do not pray in Al-Bayda’." I asked: “Where is the boundary of Al-Bayda’?” Imam عليه السلام said: "Abu Ja‘far, peace be upon him, when He عليه السلام reached Dhat Al-Jaysh, He عليه السلام would quicken his pace and would not pray until He عليه السلام reached the resting place of the Prophet صلى الله عليه وعلى آله وسلم, peace be upon him and his family." I said to Imam عليه السلام: “And where is Dhat Al-Jaysh?” Imam عليه السلام said: "Three miles before Al-Hafirah."
