Through this chain of transmission, from Muhammad ibn Ya'qub, from several of our companions, from Ahmad ibn Muhammad, from Al-Husayn ibn Sa'id, from Al-Qasim ibn Muhammad, from 'Ali ibn Abi Hamzah: He (Narrator) said: "Abu 'Abdillah عليه السلام was asked, and I was present, about a man who becomes junub (ritually impure due to seminal discharge) in his garment and then sweats in it.” Imam عليه السلام said: 'I see no harm in it.'" The man added: "He sweats to the extent that, if he wanted to, he could squeeze it out." Abu 'Abdillah عليه السلام frowned at the man and said: "If you insist, then sprinkle it with some water."
