Narrated to me by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, from Ahmad bin Muhammad, from his father, from Sa’d bin Abdullah, from Ahmad bin Muhammad, from Al-Hasan bin Mahbub, from Aban bin Uthman, from Muhammad Al-Halabi, who said: I said to Abu Abdullah عليه السلام: "A man becomes junub (ritually impure) in his garment, and he does not have any other garment with him." Imam عليه السلام said: "He should pray in it, and when he finds water, he should wash it."
